[jira] [Commented] (HBASE-12605) Metric to track delayed Flushes

    [ https://issues.apache.org/jira/browse/HBASE-12605?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14233272#comment-14233272 ] 

Elliott Clark commented on HBASE-12605:
---------------------------------------

Probably need to protect yourself from null on the wrapper. The metrics can be called before anything is initialized or while it is initializing. So checking null for each of the steps is probably needed.
