Subject [jira] [Commented] (HIVE-8362) Investigate flaky test parallel.q [Spark Branch]
Date Thu, 09 Oct 2014 22:50:34 GMT


Xuefu Zhang commented on HIVE-8362:

[~jxiang], the randomness of the output for this test is probably caused by the concurrency
issue in collecting linage info in move tasks.  Option hive.exec.parallel previously didn't
apply to move tasks but now it does (HIVE-8042). As a result, multiple move tasks can collect
linage info concurrently, accessing shared variable without synchronization.
