[jira] Commented: (HADOOP-5525) Provide a way to query job tracker
about its daemon thread's status
[ https://issues.apache.org/jira/browse/HADOOP-5525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12683799#action_12683799 ]
Amareshwari Sriramadasu commented on HADOOP-5525:
-------------------------------------------------
ThreadStatus could contain thread name, and its state: WAITING, TIMED_WAITING, RUNNABLE, BLOCKED, TERMINATED.
getClusterStatus() RPC can include required JT thread statuses.
We can provide an option bin/hadoop job -threads to display the thread statuses.
Thoughts?
