Subject [jira] [Updated] (HBASE-12631) Backport HBASE-12576 (Add metrics for rolling the HLog if there are too few DN's in the write pipeline) to 0.98
Date Wed, 10 Dec 2014 23:10:13 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Purtell updated HBASE-12631:
-----------------------------------
    Attachment: HBASE-12631-0.98.patch

Here's an updated patch that updates MetricsWAL to implement WALActionsListener, and updates
FSHLog to register its MetricsWAL instance as a listener. I looked at updating TestLogRolling,
but abandoned those changes after adding two VisibleForTesting methods and a bunch of Mockito
code that didn't yet work... Could revisit this later. The registration of MetricsWAL as an
actions listener will address what [~busbey] pointed out.
