Hemanth Yamijala commented on HADOOP-5525: ------------------------------------------ If a thread throws an uncaught exception and dies, will it be in the state TERMINATED ? The main use case is to find out what threads are not running. It would be very nice if an uncaught exception's stack trace is printed as a diagnostic. Since that information would be available from the log or out file, that may not be a mandatory thing to resolve this issue, only a nice to have feature. > Provide a way to query job tracker about its daemon thread's status > ------------------------------------------------------------------- > > Key: HADOOP-5525 > URL: https://issues.apache.org/jira/browse/HADOOP-5525 > Project: Hadoop Core > Issue Type: New Feature > Components: mapred > Reporter: Amareshwari Sriramadasu > Assignee: Amareshwari Sriramadasu > Fix For: 0.21.0 > > > Admin needs to know the status of all threads in JobTracker (whether they are > alive or not) at any point of time.
