Task Trackers accumulation
Hi
I found that the task tracker still appear on the web interface after I
killed the task tracker process, then I tried to restart it again,
But old task tracker remains. No matter how many times I repeated it
kill-restart.
Only restarting the job tracker solved my problem.

This is the regular behavior. You should see it disappear after ~10 mins of
the timeout period. Reason is that every TT starts on an ephemeral port and
therefore appears as a new TT to the JT (TTs aren't persistent members of a
cluster).
