Michael Ho resolved IMPALA-9026. -------------------------------- Fix Version/s: Impala 3.4.0 Resolution: Fixed > Add an option to use resolved IP address for Statestore subscriber > ------------------------------------------------------------------ > > Key: IMPALA-9026 > URL: https://issues.apache.org/jira/browse/IMPALA-9026 > Project: IMPALA > Issue Type: Improvement > Components: Distributed Exec > Affects Versions: Impala 3.4.0 > Reporter: Michael Ho > Assignee: Michael Ho > Priority: Minor > Fix For: Impala 3.4.0 > > > Currently, statestore subscribers currently register with statestore using > their hostnames. There may be certain deployment scenarios in which a pod may > have an IP address but its DNS entry is not available for a valid reason > (e.g. a Kubernetes pod whose readiness probe returns false). An example could > be that there could be more than one instances of an Impala component (e.g. > coordinator) but only one of them will be active at a time and the rest will > serve as backup. In which case, we still want the backup coordinator to > receive any updates from statestore but not serve any queries until the > primary coordinator fails. > To handle the case above, we may allow statestore subscribers to register > with statestore using its IP address instead of hostname. This may not work > with some existing secure deployment in which TLS is enabled between Impala > hosts as there may be mismatch between the hostname used at Thrift layer and > the certificate so this option is disabled by default. -- 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
