Lars Volker resolved IMPALA-9151. --------------------------------- Fix Version/s: Impala 3.4.0 Resolution: Fixed > Number of executors during planning needs to account for suspended executor > groupa > ---------------------------------------------------------------------------------- > > Key: IMPALA-9151 > URL: https://issues.apache.org/jira/browse/IMPALA-9151 > Project: IMPALA > Issue Type: Bug > Components: Frontend > Reporter: Lars Volker > Assignee: Lars Volker > Priority: Major > Fix For: Impala 3.4.0 > > > When configuring Impala with executor groups, the planner might see a > {{ExecutorMembershipSnapshot}} that has no executors in it. This can happen > if the first executor group has not started up yet, or if all executor groups > have been shutdown. If this happens, the planner will make sub-optimal > decisions, e.g. decide on a broadcast join vs a PHJ. In the former case, we > should have a configurable fallback cluster size to use during planning. In > the latter case, we should hang on to the last executor group size that we > had observed. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
