[jira] Issue Comment Edited: (HADOOP-3956) map-reduce doctor (Mr Doctor)

    [ https://issues.apache.org/jira/browse/HADOOP-3956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12622782#action_12622782 ]

More: 

 - Task initialization problems. As we speak I can see some tasks get stuck in initialization stage for 2 minutes or so. User can detect it by watching UI for a few hours but Mr. Doctor can improve on this for live/postmortem logs.
