Subject RE: cleanup of data when restarting Tasktracker of Hadoop
Date Tue, 29 May 2012 10:45:15 GMT
Task tracker doesn't clean any data on restart. What is the data you are storing(job oputput
or something else)? Can you check the task tracker logs or any other process removing which
is running in the same machine.

Thanks
Devaraj
