Ivan Mitic commented on HADOOP-10182: ------------------------------------- bq. Calling ActiveStandbyElector#ensureParentZNode immediately after creating the elector sounds reasonable to me. If that is the intention here, I agree it is a good idea and no need to add a config. Would modify the title/ summary in that case. Great, changed the bug title and description. Will attach the patch soon. > ZKFailoverController should ensure that parent ZNodes are pre-created during > startup > ------------------------------------------------------------------------------------ > > Key: HADOOP-10182 > URL: https://issues.apache.org/jira/browse/HADOOP-10182 > Project: Hadoop Common > Issue Type: Bug > Components: ha > Affects Versions: 2.3.0 > Reporter: Ivan Mitic > Assignee: Ivan Mitic > > Currently, a manual ZK format step is necessary before ZKFailoverController > can join leader election. This generally adds overhead on what is needed to > configure an HA cluster. My proposal is to always ensure that parent znodes > exist during startup of the ZKFailoverController. If folks do not want to > make this a default, we can put it under a config. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
