I have just upgraded my single node conf with a new one. Seemed to woork fine. Did run a balance operation.
First job failed on map63 after 4 attempts Second job failed on the same map63 Logs are empty, what is strange it is that jobs became slower. In both case map63 is executed by the master node which was working before. Suspecting memory leaks I stop the cluster and started again. Fine Run a hadoop fsck. fine 3rd time is in progress, but it looks like even slower now. Any suggestion what to do ? -- -MilleBii-
