> We found an issue in a customer environment where the HS2 crashed after a few
> days and the Java core dump contained several thousands of truststore
> reloader threads:
> "Truststore reloader thread" #126 daemon prio=5 os_prio=0
> tid=0x00007f680d2e3000 nid=0x98fd waiting on
> condition [0x00007f67e482c000]
> java.lang.Thread.State: TIMED_WAITING (sleeping)
> at java.lang.Thread.sleep(Native Method)
> at org.apache.hadoop.security.ssl.ReloadingX509TrustManager.run
> (ReloadingX509TrustManager.java:225)
> at java.lang.Thread.run(Thread.java:745)
> We found the issue to be caused by a bug in Hadoop where the
> TimelineClientImpl is not destroying the SSLFactory if SSL is enabled in
> Hadoop and the timeline server is running. I opened YARN-5309 which has more
> details on the problem, and a patch was submitted a few days back.
> In addition to the changes in Hadoop, there are a couple of Hive changes
> required:
> - ExecDriver needs to call jobclient.close() to trigger the clean-up of the
> resources after the submitted job is done/failed
> - Hive needs to pick up a newer release of Hadoop to pick up MAPREDUCE-6618
> and MAPREDUCE-6621 that fixed issues with calling jobclient.close(). Both
> fixes are included in Hadoop 2.6.4.
> However, since we also need to pick up YARN-5309, we need to wait for a new
> release of Hadoop.
