----------------------------------

I'v encounter the same problem, and filed YARN-3585.

I think it's related with leveldb thread. I also see it in your thread out.

> We faced strange issue in the cluster that NodeManager did not exitted when the SHUTDOWN event is called from NodeStatusUpdaterImpl. Taken the thread dump and verified it, but did not get much idea why NM jvm not exited. 
> At a time, for 3 NodeManger got this problem, and all the 3 NodeManager thread dump looks similar.
