Will the system time out during day presentations?

On the same day, there will be many presentations, and I want to use the switcher to transition between them. Interspersed with shorter breaks is a lengthier lunch break. Will the system time out? If so, how serious is the problem?

Can we see who answered the question in a live poll?

Good day,Would it be possible to get the live replies to a poll using an account? Or is exporting replies the sole method to view them once the poll is over? (and which accounts permit this, if any) I am grateful,

Set data type of a new added field (Expression Evaluator)

How can I change the type of a new added field in the Expression Evaluator? Because if I add a field like this: Then the field is defined as a string. But I need to have it as DATETIMEI know I could just not add this field but my goal is to make the pipeline creating not existing tables if needed. So I need to declare all attributes, even they are empty. Thanks

Include older sdc logs(sdc.log & sdc-1.log extension) in Support Bundle

Previously on all data collector below 5.X version , The behaviour was that all SDC logs were included in the Support Bundle. Now  only the current log(sdc.log) is  included and sdc-*.log logs are missing.The solution for the fix was applied post 5.4 version onwards.

View list of jars that has been loaded during SDC start up

We can see the list of jars that has been loaded during SDC start up by below configuration,If using Cloudera Manager, Please add the following to the Data Collector Advanced Configuration Snippet (Safety Valve) for sdc-env.sh configuration and restart SDC: export SDC_JAVA_OPTS="-Dstreamsets.bootstrap.debug=true ${SDC_JAVA_OPTS}" This will tell us what jars are being picked up in the classpath when SDC starts.  The output will appear in stdout.log of the Data Collector process. If  we are using standalone SDC, we can add the above snippet directly to sdc-env.sh ($SDC_HOME/libexec)and restart the sdc.

DATE type in Oracle origin database is casted into DATETIME on Snowflake?

Our goal is to sync between Oracle and Snowflake with CDC Oracle. Some of our source tables in Oracle are defined as DATE. So we created this tables also in Snowflake with the same type, DATE.  But now I get this error message:  But in this case the field ACTIVITY_TIME is DATE on Oracle and Snowflake.Later I noticed that we don’t have any problem if I convert all DATE fields into DATETIME attributes on Snowflake. But looking in the documentation, there is nothing mentioned that we have to use DATETIME in such cases. The type DATE is explicitly mentioned as supported type. Does anyone had the same issues? I mean it’s not so unusual to use the DATE type in a database

GCP: credential:get function - Are there limitations where this function can be used?

Hello, One of my customer is using StresmSets to access secrets saved in GCP. The SDC setup and GCP secrets setup is correct. For example,  I have used secrets like below successfully in JDBC producer stage’s credential tab and pipeline works fine, picks up latest version of the secret as expected. ${credential:get("gcp", "group@org", "dbuser?latest")}${credential:get("gcp", "group@org", "dbpass?latest")}Now, they want to read a secret for which a json file was uploaded as value, and they want to extract credential information from this json.  I tried to use credential:get in an Expression evaluator but it gave an error. (was planning to add more processors after this to extract userid and password from the json returned by credential:get) How can i use secret like this in my StreamSets pipeline? Thanks!

ADLS Gen 2 Legacy

[ADLS Gen 2 Changes]:In Data Collector Version 5.5.0 a change was made which altered how the ADLS Gen 2 stage functioned. Previously the ADLS Gen 2 Stage utilized the Hadoop FS to access resources. This change also split the stage into the respective resources they access: ADLS Gen 2 and Azure Blob Storage. For additional information surrounding this change please review the patch notes linked below: Ref 1: Patch NotesRef 2: Available Stage Comparison [Legacy ADLS Gen 2]:Additionally, the ADLS Gen 2 Legacy stage which used Hadoop FS is also still available to be utilized.** It should be noted though that when exporting a pipeline made on a version prior to 5.5 into later Data Collectors that the (Legacy) tag will not be present on the stage information. However, the description of the stage will still relay the method with which the resource is accessed. When the (Legacy) stage is selected in a current pipeline it can be identified as seen in the image below

Excessively large engine-$$.out file in the /tmp directory

The Issue:  Data Collector has created a file in the /tmp directory that is growing to an excessive size and is taking up space.  The purpose of this file is to serve as a location for stdout from a running Data Collector. Under normal circumstances, this file does not receive much data and should not grow to a large size. Specifically, the rotatelogs is used to limit the size of this file to ~10mb.  However, there are a few instances where this file will receive more data than usual, or grow to an excessively large size.  Adding certain Java parameters to your $SDC_HOME/libexec/sdc-env.sh file can result in extra output being sent to this /tmp file. This output is often useful for debugging, but can fill the file up quickly. An example of this might be the -Djavax.net.debug=ssl,handshake parameter used to debug SSL connections.  If the rotatelogs utility is not currently available on your machine, the /tmp/engine-$$.out file may continue to grow past the limited size of ~10mb.  The So

HTTP Processor for POST request clearing header values

Hello! I’m using record header attributes as variables. For example, during pipeline execution, saving ${time:now()} in a header attribute with an Expression Evaluator, to be used in other stages. This is no problem for HTTP GET requests, as the data gets aggregated into existing records. The problem is with HTTP Processor for POST requests, where the response overwrites all existing data from before, body and headers.Is there anyway around this? I’m trying to use this header attribute value that I saved to be used in anohter HTTP POST request after the one I just mentioned, but the value is lost. Thanks in advance!

SDC 5.7.x - Orchestration pipeline calling a Job Template does not function properly

Environment:StreamSets Data Collector (SDC) 5.7.0 & 5.7.1 An orchestration pipeline which uses Start Jobs stages The orchestration stage starts a job using a Job Template The orchestration stage is configured with the Run in Background setting disabled  Issue:In StreamSets Data Collector (SDC) 5.7.0 and 5.7.1, orchestration pipelines that use a Start Jobs stage to start a job using a Job Template do not function properly when Run in Background is disabled. With this configuration, the pipeline should wait for the job to complete before moving to the next stage, but instead the pipeline starts the job and immediately moves on, which can cause unexpected results for downstream jobs. Resolution:There is a fix planned for this issue in the SDC 5.8.0 release. In the short term, if your organization has an active support contact, you can contact StreamSets Support to obtain a patch to resolve the issue.

SCH 3.x - Sharing Settings - Users/Group not showing up in the search box

IssueWhen updating the sharing settings for pipelines, jobs, etc. typing in a user or group that is known to exist in the organization doesn’t show up in the search box.ResolutionThis occurs when there are more than 50 users and/or groups. Control Hub preloads 50 users and groups for the purposes of autocomplete. If a user or group doesn’t show up, you can type in the full username (user@org) or group name (group@org) and click the add button, and it will work.NoteThis issue is specific to legacy StreamSets Control Hub 3.x. In Platform, the search box has been improved and should autocomplete for all users and groups.

Azure_02 Error when creating an Azure Connection in Control Hub

The Issue:  When attempting to create a Connection for an Azure account, you receive the following error message: ADLS_02 - Failed to connect to Azure Data Lake Store: ‘Operation failed: “An HTTP header that’s mandatory for this request is not specified”,400,PUT, <URL>The Solution:  This error could potentially indicate that the Connection type set in Control Hub and the Azure account type do not match. When using a Data Collector version that is higher than 5.4, you are presented with a number of options when creating a new connection to Azure. These options include: Azure Blob Storage Azure Data Lake Storage Gen2 Azure Synapse When this error is encountered, before troubleshooting further it is important to first check that the connection type that was chosen here matches the Azure Account type you are connecting to. This can be verified by checking the Azure Account FQDN. For example: An FQDN like example.dfs.core.windows.net would be used for an Azure Data Lake Storage Gen2 c

I am using the python SDK and I when I use the method “.committer” or “.last_modified_by” on a pipeline object, I am expecting to get back an email that I am able to see under “Committed By” on the platform. However, I get back a long string that I can’t make out:sudo code of what I am doing: sch = ControlHub(credential_id="cred_id,token = token)print(sch.pipelines.get(commit_id = commit_id).last_modified_by) and instead of getting a string of an email returned, I am getting something like this returned:a83b3195-61f4-11ee-a6e4-…..@b5f95dcd-5f00-11ec-b405-…… Would you happen to know how I can turn this string into a valid email? I couldn’t find anything on this topic in the docs.
