Blacklisting decisions are local to a given coordinator > and are not included in statestore updates. > The intention is to allow coordinators to be more aggressive about > deciding that an exeutor is unhealthy or unavailable, to minimize > failed queries in environments where cluster membership may be more > variable, rather than having to wait on the statestore heartbeat > mechanism to decide that the executor is down. > {quote} -- 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
