We can see the list of jars that has been loaded during SDC start up by below configuration,

1. 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.
2. If  we are using standalone SDC, we can add the above snippet directly to sdc-env.sh ($SDC_HOME/libexec)and restart the sdc.
