Hi, I'm running hadoop map-reduce in clustering, and I've a Reduce Task that it remains in the state COMMIT_PENDING, and it doesn't finish. This is happening because I've made some changes to the Hadoop MR. I'm trying to solve my problem, but I don't understand what's happens after the COMMIT_PENDING.
I know that when a task is in COMMIT_PENDING, is requesting something to the TaskTracker or the JobTracker, for the task become SUCCESSFUL. But, in detail, I don't know nothing. Can anyone explain in more details what's happening? Thanks, -- xeon
