Hi all,
I am on spark 2.4.4 and using scala 2.11.12, and running cluster mode on mesos. I am ingesting from an oracle database using spark.read.jdbc. I am seeing a strange issue where spark just hangs and does nothing, not starting any new tasks. Normally this job finishes in 30 stages but sometimes it stops at 29 completed stages and doesn’t start the last stage. The spark job is idling and there is no pending or active task. What could be the problem? Thanks. -- Cheers, Ruijing Li
