    [ https://issues.apache.org/jira/browse/YARN-6166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15860342#comment-15860342

Daniel Templeton commented on YARN-6166:
----------------------------------------

I assigned the JIRA to you, [~genericuser].  {{interrupt()}} isn't a static method, so I doubt
that patch will compile.  You'll have to get the current thread to call {{interrupt()}} on
it.  See https://www.ibm.com/developerworks/library/j-jtp05236/.
