Subject [jira] [Commented] (HDFS-9064) NN old UI (block_info_xml) not available in 2.7.x
Date Thu, 24 Sep 2015 15:42:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14906526#comment-14906526

Haohui Mai commented on HDFS-9064:

There are two reasons that the jsp is removed:

(1) Yes, there's security issues in block_info_xml.jsp.
(2) The output itself is problematic. The information, particularly, the filename of the block,
is inaccurate due to snapshots and truncate.

>                 URL: https://issues.apache.org/jira/browse/HDFS-9064
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: HDFS
>    Affects Versions: 2.7.0
>            Reporter: Rushabh S Shah
>            Assignee: Kanaka Kumar Avvaru
>            Priority: Critical
> In 2.6.x hadoop deploys, given a blockId it was very easy to find out the file name and
the locations of replicas (also whether they are corrupt or not).
> This was the REST call:
> {noformat}
>  http://<nnAddress>:<port#>/block_info_xml.jsp?blockId=xxx
> {noformat}
> But this was removed by HDFS-6252 in 2.7 builds.
> Creating this jira to restore that functionality.
