[jira] [Commented] (HBASE-17478) Avoid sending FSUtilization reports to master when quota support is not enabled

["Ted Yu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-17478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15872011#comment-15872011 ] 

Ted Yu commented on HBASE-17478:
--------------------------------

{code}
541	    if (null == regionSizes) {
542	      return new HashMap<>();
{code}
You can wrap Collections.unmodifiableMap() around an empty map and use it as singleton.
This way you don't need to create map every time.

> Trivial little change to make sure that the RS's do not send the filesystem utilization reports to the master when hbase.quota.enabled=false and, similarly, that the master gracefully handles these reports when the feature is not enabled.
