    I’m running Ambari 1.4.1 and I recently decommissioned a datanode via Ambari. All seem to go well, as the the Namenode UI(hostname:50070) is now showing the correct number of live nodes(7). However, Ambari is still showing 8 datanodes in the dashboard, but does say ‘Decommissioned’ under the host.

    How do I get ambari to reflect the correct number of datanodes?

    Kenny,

    I’ve tried that and even from a browser I’ve never used to access ambari. I believe this issue has blended into another issue that is being worked on a different thread:

    Hi Ray,

    It sounds like browser cache is not clear after the upgrade. Could you please try to clear the web browser cache and try again?

    Thanks,
    Kenny

    Well,

    I’ve upgraded successfully, however, now I can’t login to ambari. When I go to hostname:8080 I get ‘Loading’ .

    Any ideas?

    Jeff,

    Thanks for the reply.

    So, the expected behavior is once it is decommissioned, ambari then reflects this automatically, there is no other action required?

    There might have been a bug related to that in Ambari 1.4.1 but I can’t seem to find the JIRA.

    The latest Ambari is 1.4.4. Want to try upgrading?
