It happens sporadically when stopping YarnClient.
Looking at the code in Client's 'unrefAndCleanup' its not immediately obvious
why and who throws the interrupt but in any event it should not be logged as
ERROR. Probably a WARN with no stack trace.
Also, for consistency and correctness you may want to Interrupt current
thread as well.

Mit Desai commented on YARN-1965:
-
Overall patch Looks good. Few minor nits.
* There should be a space between () and { here
{{public static final ExecutorService getClientExecutor(){}}
* In testStandAloneClient(), we need spaces near the brackets. Change
{{}finally{}} to {{} finally {}}
* In testConnectionIdleTimeouts(), we need space near the brackets. Change
{{}finally{}} to {{} finally {}}
* testInterrupted needs to be indented.
* In doErrorTest, testRTEDuringConnectionSetup stopping the client before the
server makes more sense. Swap the stop calls in finally block
* In testSocketFactoryException,testIpcConnectTimeout {{client.stop()}} should
be within finally block
* Is there a need to move {{Client client = new Client(LongWritable.class,
conf, spyFactory);}} in testRTEDuringConnectionSetup?

Should this be a hadoop common issue? Looks like all the changes are in hadoop
common project.

{code}
It happens sporadically when stopping YarnClient.
Looking at the code in Client's 'unrefAndCleanup' its not immediately obvious
why and who throws the interrupt but in any event it should not be logged as
ERROR. Probably a WARN with no stack trace.
Also, for consistency and correctness you may want to Interrupt current
thread as well.
