Zhijie Shen commented on YARN-3562:
-----------------------------------
I also see a lot of NoSuchMethodError here too. I think jenkins build on branch
has some bug.
> unit tests failures and issues found from findbug from earlier ATS checkins

> *Issues reported from MAPREDUCE-6337* :
> A bunch of MR unit tests are failing on our branch whenever the mini YARN
> cluster needs to bring up multiple node managers.
> For example, see
> https://builds.apache.org/job/PreCommit-MAPREDUCE-Build/5472/testReport/org.apache.hadoop.mapred/TestClusterMapReduceTestCase/testMapReduceRestarting/
> It is because the NMCollectorService is using a fixed port for the RPC (8048).
> *Issues reported from YARN-3044* :
> Test case failures and tools(FB & CS) issues found :
> # find bugs issue : Comparison of String objects using == or != in
> ResourceTrackerService.updateAppCollectorsMap
> # find bugs issue : Boxing/unboxing to parse a primitive
> RMTimelineCollectorManager.postPut. Called method Long.longValue()
> Should call Long.parseLong(String) instead.
> # find bugs issue : DM_DEFAULT_ENCODING Called method new
> java.io.FileWriter(String, boolean) At
> FileSystemTimelineWriterImpl.java:\[line 86\]
