Description

The original idea raised from Michael here: https://issues.apache.org/jira/browse/HDFS-1605?focusedCommentId=13846972&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13846972

It would be better to have a lower interval value especially for online service, like HBase.
