Gopal V commented on HIVE-11165: -------------------------------- [~pxiong]: this doesn't always happen - I have to increase concurrency to trigger this. The current test workaround is that there's a RandomOrderController in my tests so that it doesn't plan the same query (with the same vertex names, predicates etc) at the same time. > Calcite planner might have a thread-safety issue compiling in parallel > ---------------------------------------------------------------------- > > Key: HIVE-11165 > URL: https://issues.apache.org/jira/browse/HIVE-11165 > Project: Hive > Issue Type: Bug > Components: CBO > Affects Versions: 2.0.0 > Reporter: Gopal V > Assignee: Laljo John Pullokkaran > Attachments: RunJar-2015-06-30.snapshot > > > After about 6 minutes trying to plan a query, the HiveServer2 was killed to > restore functionality to a test run. > The HEP planner is stuck on a TopologicalOrder traversal and there were no > queries being fed into the HiveServer2 after it got stuck. > TPC-DS query13 was the query in question, at 4 way parallel, which triggered > the issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
