Subject [jira] [Commented] (HDFS-13963) NN UI is broken with IE11
Date Tue, 09 Oct 2018 13:51:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16643460#comment-16643460

Ayush Saxena commented on HDFS-13963:

{quote}it seems IE9 is no longer supported by MS, hence we should just align with the latest
version of IE
I agree and as per the reference that [~elek] got for us.I even don't think this change would
have any adverse impact since IE-9 seems to be rarely used in the present scenario.

Thanks [~vinayrpet] for the suggestion.Have uploaded the updated patch.I am also not sure
about IE-9 compatibility.Since I even couldn't get it due to compatibility issues.

> 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
> {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.
