      Description

      Pig tez local mode tests hang under some scenario. I attached several stack trace of hanging tests.

      By setting "tez.am.inline.task.execution.max-tasks", the test does not hang. However, we cannot make it general since Pig backend code is not designed to be multithread-safe.
