["Chris Douglas (JIRA)" <ji...@apache.org>]

Chris Douglas resolved YARN-3192.
---------------------------------
    Resolution: Not a Problem

Calling {{System.exit(-1)}} is not an acceptable way to shut down the RM. Please review the surrounding code.

I'm going to close this, until we can tie a bug to this code. Graceful shutdown is difficult to effect, and this issue's scope is too narrow to contribute to it.

[~brahmareddy], many of the JIRAs you're filing appear to be detected by automated tools. If the interrupt handling here can cause hangs, HA bugs, inconsistent replies to users, etc. then please file reports on the consequences, citing this as the source.
