             Summary: NN UI is broken with IE11
                 Key: HDFS-13963
                 URL: https://issues.apache.org/jira/browse/HDFS-13963
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode, ui
    Affects Versions: 3.1.1
            Reporter: Daisuke Kobayashi


Internet Explorer 11 cannot correctly display Namenode Web UI while the NN itself starts successfully. I have confirmed this over 3.1.1 (latest release) and 3.3.0-SNAPSHOT (current trunk) that the following message is shown.

{code}
Failed to retrieve data from /jmx?qry=java.lang:type=Memory, cause: SyntaxError: Invalid character
{code}

Apparently, this is because {{dfshealth.html}} runs as IE9 mode by default.

{code}
<meta http-equiv="X-UA-Compatible" content="IE=9" />
{code}

Once the compatible mode is changed to IE11 through developer tool, it's rendered correctly.
