> Fix SSLFactory truststore reloader thread leak in TimelineClientImpl
> --------------------------------------------------------------------
>
> Key: YARN-5309
> URL: https://issues.apache.org/jira/browse/YARN-5309
> Project: Hadoop YARN
> Issue Type: Bug
> Components: timelineserver, yarn
> Affects Versions: 2.7.1
> Reporter: Thomas Friedrich
> Assignee: Weiwei Yang
> Priority: Blocker
> Attachments: YARN-5309.001.patch, YARN-5309.002.patch,
> YARN-5309.003.patch, YARN-5309.004.patch, YARN-5309.005.patch,
> YARN-5309.branch-2.7.3.001.patch, YARN-5309.branch-2.8.001.patch
>
>
> We found a similar issue as HADOOP-11368 in TimelineClientImpl. The class
> creates an instance of SSLFactory in newSslConnConfigurator and subsequently
> creates the ReloadingX509TrustManager instance which in turn starts a trust
> store reloader thread.
> However, the SSLFactory is never destroyed and hence the trust store reloader
> threads are not killed.
> This problem was observed by a customer who had SSL enabled in Hadoop and
> submitted many queries against the HiveServer2. After a few days, the HS2
> instance crashed and from the Java dump we could see many (over 13000)
> threads like this:
> "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)
> HiveServer2 uses the JobClient to submit a job:
> Thread [HiveServer2-Background-Pool: Thread-188] (Suspended (breakpoint at
> line 89 in
> ReloadingX509TrustManager))
> owns: Object (id=464)

> Driver.execute() line: 1412
> For every job, a new instance of JobClient/YarnClientImpl/TimelineClientImpl
> is created. But because the HS2 process stays up for days, the previous trust
> store reloader threads are still hanging around in the HS2 process and
> eventually use all the resources available.
> It seems like a similar fix as HADOOP-11368 is needed in TimelineClientImpl
> but it doesn't have a destroy method to begin with.
> One option to avoid this problem is to disable the yarn timeline service
> (yarn.timeline-service.enabled=false).
