Hi, I use cloudera's distribution for hadoop. What I see is that a small fraction of maps get stuck at 100%. They show up as 100% but continue running. After a lot of delay, they succeed finally but it takes a while, like 10 mins from the time when they show up as 100%.
We recently reformatted our hadoop fs. Could it be related to that ? Thanks Morpheus: Do you believe in fate, Neo? Neo: No. Morpheus: Why Not? Neo: Because I don't like the idea that I'm not in control of my life.
