OutOfMemoryError in RegionServer
--------------------------------
Key: HBASE-1988
URL: https://issues.apache.org/jira/browse/HBASE-1988
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.2
Environment: Java 1.6.0_16 64bit on CentOS with 3000M max heap
Reporter: Stefan Will
RegionServers tend to die with an OutOfMemoryError under load. I expected this
problem to go away with the fix for HBASE-1927 in 0.20.2 RC1, but it's still
happening. Also, when this happens the cluster becomes unresponsive, even once
the load on the machines has gone back down. Interestingly there are lots and
lots of scanner lease expired messages right before the OOM.
