> Java client timeout exceptions aren't useful
> --------------------------------------------
>
> Key: KUDU-1734
> URL: https://issues.apache.org/jira/browse/KUDU-1734
> Project: Kudu
> Issue Type: Improvement
> Components: client
> Affects Versions: 1.0.0
> Reporter: Matthew Jacobs
> Labels: client, impala, usability
>
> When a timeout occurs in the Java client, it throws exceptions that are very verbose and hard to make use of.
> For example:
> {code}
> CAUSED BY: NonRecoverableException: Timed out after 1ms when joining Deferred@1214130230(state=PENDING, result=null, callback=get tablet locations from the master for table Kudu Master -> release master lookup permit -> retry RPC -> org.apache.kudu.client.AsyncKuduClient$4@1da21658 -> wakeup thread Thread-7, errback=passthrough -> release master lookup permit -> retry RPC after error -> passthrough -> wakeup thread Thread-7)
> CAUSED BY: TimeoutException: Timed out after 1ms when joining Deferred@1214130230(state=PENDING, result=null, callback=get tablet locations from the master for table Kudu Master -> release master lookup permit -> retry RPC -> org.apache.kudu.client.AsyncKuduClient$4@1da21658 -> wakeup thread Thread-7, errback=passthrough -> release master lookup permit -> retry RPC after error -> passthrough -> wakeup thread Thread-7)
> {code}
> Most of the information isn't useful to the caller.
