Jean-Daniel Cryans resolved KUDU-1734.
--------------------------------------
Resolution: Fixed
Assignee: Jean-Daniel Cryans
Fix Version/s: 1.1.0
Target Version/s: 1.1.0
With https://gerrit.cloudera.org/#/c/4871/ I'm going to close this as solved.
Tracing is not in yet but I removed the places where the join() could timeout
before the operation itself gets a timeout. This means that now we'll have more
information, even without full traces.

> 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

> RPC after error -> passthrough -> wakeup thread Thread-7)
> {code}
> Most of the information isn't useful to the caller.
