-------------------------------
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.
