> Project: Apache Tez
> Issue Type: Bug
> Reporter: Daniel Dai
> Attachments: TestMultiQuery.log, TestMultiQueryBasic.log,
> 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.
