[jira] [Commented] (ACCUMULO-3776) Cannot access Accumulo Monitor UI

["Josh Elser (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-3776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14531305#comment-14531305 ] 

Josh Elser commented on ACCUMULO-3776:
--------------------------------------

Thanks for filing [~zmarsh13]. Can you verify that the copy of {{accumulo-env.sh}} on the host running the Monitor actually has the expected value that you specified in the template?

If I remember my netstat output, it doesn't look like the server actually bound itself to all interfaces, so it'll only be accessible via {{39.0.16.3:50095}}. I would expected to see {{0.0.0.0:50095}}.

Meanwhile, I'll double check locally -- as far as I know, this env option has been working for me w/o Ambari.
