Zack Marsh created ACCUMULO-3776:
------------------------------------

             Summary: Cannot access Accumulo Monitor UI
                 Key: ACCUMULO-3776
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3776
             Project: Accumulo
          Issue Type: Bug
         Environment: ambari-2.1.0-376, hdp-2.3.0.0-1880, sles11sp3
            Reporter: Zack Marsh


After installing Accumulo on my cluster, I find that I am unable to access the Accumulo Monitor
UI at <hostname FQDN>:50095. 

Instead of a server error the page simply will not load.

I'm seeing that the Accumulo Monitor is binding to the localhost:

I implemented the work-around specified in ACCUMULO-1985, and added the following line to
accumlo-env template in Ambari:
{code}
export ACCUMULO_MONITOR_BIND_ALL="true"
{code}

After restarting all Accumulo components this issue remains.
