Thomas Graves commented on MAPREDUCE-3851:
------------------------------------------
in the original jetty detection jira - MAPREDUCE-2529 - Chris had asked to
keep it undocumented see
https://issues.apache.org/jira/browse/MAPREDUCE-2529?focusedCommentId=13044180&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13044180
It appears that none of the configuration similar to this are documented so
kept with that theme.
> Allow more aggressive action on detection of the jetty issue

> MAPREDUCE-2529 added the useful failure detection mechanism. In this jira, I
> propose we add a periodic check inside TT and configurable action to
> self-destruct. Blacklisting helps but is not enough. Hung jetty still accepts
> connection and it takes very long time for clients to fail out. Short jobs
> are delayed for hours because of this. This feature will be a nice companion
> to MAPREDUCE-3184.
