Description

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.

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

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

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

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