Christian Kunz commented on HADOOP-2907:
----------------------------------------
When we ran into the same problem with #810 a month ago on a different cluster
it was not clear to us whether we should report it immediately because it was a
trunk release and it might have been just a transient problem. We wanted to
wait for a stable release and check whether it stlil happens.
BTW, I checked the logs:
Around 2% of datanodes had OutOfMemoryError exceptions. By itself, it would
probably be not much of a problem, but it happened that some of the datanodes
went out within a short time of period such that we lossed a few blocks.
