I have problem with reduce tasks ending like this:
Task attempt_201111250441_0009_r_000001_1 failed to report status for 602 seconds. Killing!

Every reduce tasks running on particular block ends like this.

can it be caused that list for one key is too long or because processing of one list item takes too long?

Can you put here the output logs of your NN and DN servers?
Regards
