Subject [jira] Commented: (HDFS-1573) LeaseChecker thread name trace not that useful

Todd Lipcon commented on HDFS-1573:
-----------------------------------

I don't think so. I had a patch around somewhere, I'll see if I can find it and upload it
(apparently forgot to when I made the JIRA)

> The LeaseChecker thread in DFSClient will put a stack trace in its thread name, theoretically
to help debug cases where these threads get leaked. However it just shows the stack trace
of whoever is asking for the thread's name, not the stack trace of when the thread was allocated.
I'd like to fix this so that you can see where the thread got started, which was presumably
its original intent.
