[jira] [Created] (TEZ-1928) Tez local mode hang in Pig tez local mode

Daniel Dai created TEZ-1928:
-------------------------------

             Summary: Tez local mode hang in Pig tez local mode
                 Key: TEZ-1928
                 URL: https://issues.apache.org/jira/browse/TEZ-1928
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Daniel Dai
         Attachments: TestScalarAliasesLocal.log

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.
