Subject [jira] [Commented] (HDFS-2677) HA: Web UI should indicate the NN state
Date Wed, 14 Dec 2011 18:09:30 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13169548#comment-13169548

Aaron T. Myers commented on HDFS-2677:

bq. Is there a programmatic way to get at this, e.g., via JMX (FSNamesystemInfo already reveals
a bunch) or metrics?

Hey Phil, check out HDFS-2510, which will add what you're asking about and a few more metrics.
