-----------------------------------
Summary: Fix incorrect threaded ObjectStore usage in
TestObjectStore
Key: HIVE-22351
URL: https://issues.apache.org/jira/browse/HIVE-22351
Project: Hive
Issue Type: Bug
Affects Versions: 4.0.0
Reporter: John Sherman
Assignee: John Sherman
Fix For: 4.0.0
TestObjectStore#testConcurrentDropPartitions shares the same ObjectStore object
across two threads doing concurrent drops. ObjectStore isn't thread safe. I've
seen occasional deadlocks where one thread is rolling back and another is
trying to commit with each thread waiting on the other (one is holding an
object lock via a synchronized method and another is holding the
ExecutionContextThreadedImpl lock). I think the intent is to test dropPartition
behavior and ensure the backing DB receives a rollback or abort on conflicting
drops.
