TestDFSIO program running with write option , number of files is 250 and file size is 256 MB (block size is also 256 MB)
NN went to safemode so JT was trying to connect to NN continuously..
later NN switched and it became proper..
Then JT is trying to kill some taskattempts and it's not able to do so as the task is not in TaskInProgress state at TT side
Also TaskTracker didnt respond before 10mins to it was declared lost marking all the tasks on that.
Has someone faced similar issue?
I couldnt reproduce this problem again.
Anyone can give any directions?
Thanks in advance.
