Ted Yu created AMBARI-18574:
-------------------------------
Summary: Set hbase.hregion.memstore.chunkpool.maxsize to 1.0
Key: AMBARI-18574
URL: https://issues.apache.org/jira/browse/AMBARI-18574
Project: Ambari
Issue Type: Bug
Reporter: Ted Yu
The default value for hbase.hregion.memstore.chunkpool.maxsize is:
{code}
final static float POOL_MAX_SIZE_DEFAULT = 0.0f;
{code}
This would result in chunk pool being disabled, leading to excessive
MemStoreLAB chunk allocations.
Ambari should set the value to 1.0
