Nick Dimiduk created HBASE-10792: ------------------------------------ Summary: RingBufferTruck does not release its payload Key: HBASE-10792 URL: https://issues.apache.org/jira/browse/HBASE-10792 Project: HBase Issue Type: Bug Components: Performance, wal Affects Versions: 0.99.0 Reporter: Nick Dimiduk
Run a write-heavy workload (PerfEval sequentialWrite) out of a trunk sandbox and watch as HBase eventually dies with an OOM: heap space. Examining the heap dump shows an extremely large retained size of KeyValue and RingBufferTrunk instances. By my eye, the default value of {{hbase.regionserver.wal.disruptor.event.count}} is too large for such a small default heap size, or the RBT instances need to release their payloads after consumers retrieve them. -- This message was sent by Atlassian JIRA (v6.2#6252)
