We have pipelines parsing json files and insert data into impala via JDBC Query Consumer. Then we add Kerberos authentication on cluster and change JDBC Connection String with parameters required by kerberos and connect at start without problem. But then of X minutes this pipeline disconect with error some like:

Pipeline Status: STOPPING_ERROR: com.streamsets.pipeline.api.StageException: QUERY_EXECUTOR_002 - Can't open connection: HikariPool-328 - Connection is not available, request timed out after 30000ms.

This problem occurr in all pipelines, then of 3 minutes aprox. this pipelines connect again.

Any idea where is problem?

Thanks, Luis
