Raghu Angadi commented on HADOOP-2669:
--------------------------------------
Thanks Pete.
No suspects yet but surely looks like a bug. Could you grep for "Removing
lease" around the log for "/tmp/1050617226/ds=2008-02-18/SomeTable/part-00015"
and grep for one its blocks, say 2853191854023133101 (to see what happened to
it) . Not yet sure if client side failures are related.
