Subject RE: New NameNode UI does not support Internet Explorer
Date Fri, 07 Feb 2014 07:15:32 GMT
I found the problem.

Some problem of jquery with IE8 and IE9 on Windows 7.

There were 2 issues.
1. in dfshealth.js there was an extra comma(,) in array definition and this was causing a
js error.
    var BEANS = [
      {"name": "nn",      "url": "/jmx?qry=Hadoop:service=NameNode,name=NameNodeInfo"},
      {"name": "nnstat",  "url": "/jmx?qry=Hadoop:service=NameNode,name=NameNodeStatus"},
      {"name": "fs",      "url": "/jmx?qry=Hadoop:service=NameNode,name=FSNamesystemState"},
      {"name": "mem",     "url": "/jmx?qry=java.lang:type=Memory"},
    ];
    
   Removing extra comma(,) solved first issue.
   Found hint about this here 
       http://stackoverflow.com/questions/12573470/each-in-ie8-seems-to-get-counted-one-too-many-times

2. in dfshealth.html and explorer.html JSON object was not being initialized.
    Adding 
           <meta http-equiv="X-UA-Compatible" content="IE=EDGE" />
    to both html files solved issue.

    Found this here,
      http://stackoverflow.com/questions/4715373/json-object-undefined-in-internet-explorer-8-dom

I will post a patch for the same in Jira soon.

Could the difference be due to versions of Internet explorer ?
