Subject [jira] [Updated] (HDFS-4059) Add number of stale DataNodes to metrics
Date Tue, 16 Oct 2012 19:51:04 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4059?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Suresh Srinivas updated HDFS-4059:

       Resolution: Fixed
    Fix Version/s:     (was: 1.1.0)
     Release Note: 
This jira adds a new metric with name "StaleDataNodes" under metrics context "dfs" of type
Gauge. This tracks the number of DataNodes marked as stale. A DataNode is marked stale when
the heartbeat message from the DataNode is not received within the configured time ""dfs.namenode.stale.datanode.interval".

Please see hdfs-default.xml documentation corresponding to ""dfs.namenode.stale.datanode.interval"
 for more details on how to configure this feature. When this feature is not configured, this
metrics would return zero.

     Hadoop Flags: Reviewed
           Status: Resolved  (was: Patch Available)

I committed the patch to branch-2 and trunk. Thank you Jing.
