> Add zkManager.exists(path) check to ZKConfigurationStore:getZkData() and

> Key: YARN-11924
> URL: https://issues.apache.org/jira/browse/YARN-11924
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Ferenc Erdelyi
> Assignee: Ferenc Erdelyi
> Priority: Major
> Labels: pull-request-available
>
> If the 'yarn resourcemanager -format-conf-store' command is issued while one
> of the RMs is in a starting state, the RM may fail. This occurs because the
> /confstore/CONF_STORE path may not yet exist (because of YARN-11551).
> Alternatively, if the confstore is in the process of being written, the
> getZkData method returns a null value, causing the crash.
> To prevent this, added a re-try mechanism before giving up.
