Daryn Sharp commented on MAPREDUCE-5117:
----------------------------------------
I'm not sure it's related to MAPREDUCE-5088. The error is occurring in this
block of code:
{code}
MRClientProtocol histProxy = instantiateHistoryProxy(conf,
SecurityUtil.getTokenServiceAddr(token));
try {
RenewDelegationTokenRequest request = Records
.newRecord(RenewDelegationTokenRequest.class);
request.setDelegationToken(dToken);
return histProxy.renewDelegationToken(request).getNextExpirationTime();
} finally {
stopHistoryProxy(histProxy);
}
{code}
It's blowing up in the finally clause that histProxy is not a proxy. The
caught exception has been swallowed, but since histProxy isn't a proxy it's
almost certainly failing on histProxy.renewDelegationToken.
So the question is how is histProxy not a proxy??

> Key: MAPREDUCE-5117
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5117
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: security
> Affects Versions: 2.0.4-alpha
> Reporter: Roman Shaposhnik
> Priority: Blocker
> Fix For: 2.0.4-alpha

> Attachments: yarn.log

> It seems that the HSClientProtocolPBClientImpl should implement Closeable as
> per the attached stack trace. The problem can be observed on a cluster
> running the latest branch-2.0.4-alpha with MAPREDUCE-5088 applied on top. The
> easiest way to reproduce it is to run an oozie pig job:
> {noformat}
> $ oozie job -oozie http://`hostname -f`:11000/oozie -run
> -DjobTracker=`hostname -f`:8032 -DnameNode=hdfs://`hostname -f`:17020
> -DexamplesRoot=examples -config /tmp/examples/apps/pig/job.properties
> {noformat}
> Please also note that I can successfully submit simple jobs (Pi/Sleep) from a
> command line using hadoop jar command. Thus it *seems* related to
> MAPREDUCE-5088 change.
