[jira] [Created] (AMBARI-18574) Set hbase.hregion.memstore.chunkpool.maxsize to 1.0

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
