Sahil Takiar commented on IMPALA-10240: --------------------------------------- Would be nice to document what exactly happens when a node is remove from the cluster membership - e.g. all queries running on that node are either cancelled or retried (they are retried if transparent query retries are enabled). This should cover the scenario where a coordinator fails as well (e.g. all queries die, and the executors eventually timeout all fragments and cancel them). > Impala Doc: Add docs for cluster membership statestore heartbeats > ----------------------------------------------------------------- > > Key: IMPALA-10240 > URL: https://issues.apache.org/jira/browse/IMPALA-10240 > Project: IMPALA > Issue Type: Sub-task > Reporter: Sahil Takiar > Priority: Major > > I don't see many docs explaining how the current cluster membership logic > works (e.g. via the statestored heartbeats). Would be nice to include a high > level explanation along with how to configure the heartbeat threshold. -- 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
