On pipeline validation or start, you see this exception:
com.streamsets.datacollector.store.PipelineStoreException: CONTAINER_0209 - Pipeline state file '/data/runInfo/myPipeline/0/pipelineState.json' doesn't exists.
The only workaround how to get around this error is to recreate your pipeline. Before doing so, check to see if the following files exist for the pipeline in question:
By running the following command:
ls -ltrR <SDC_DATA_DIR>
If all four files are not present then the pipeline has been deleted, possibly because
- One of your users has deleted the pipeline while you are working on the same pipeline and the REST call from UI to fetch the pipeline fails
- Someone may have stopped/removed the pipeline from StreamSets Control Hub, which will delete the pipeline from StreamSets Data Collector.
