Task Trackers running out of memory
kishore raju 2013-03-15, 19:03

 We are having an issue where multiple Task Trackers are running out of
memory. I have collected HeapDump on those TaskTrackers to analyze further.
They are currently running with 1GB Heap. we are planning to bump it to
2GB, Is there a way that we can find which Job is causing this OOM on TT's ?

Any help is appreciated.
