------------------------------------
Resolution: Duplicate
> ZKRMStateStore: Better handling of operation failures
> -----------------------------------------------------
>
> Key: YARN-2063
> URL: https://issues.apache.org/jira/browse/YARN-2063
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.4.0
> Reporter: Karthik Kambatla
> Assignee: Karthik Kambatla
> Priority: Critical
>
> Today, when a ZK operation fails, we handle connection-loss and
> operation-timeout the same way. This could definitely use some improvements:
> # Add special handling for other error codes
> # Connection-loss: Nullify zkClient, so a new connection is established
> # Operation-timeout: Retry a few times with exponential delay?
