Subject [jira] [Commented] (HDFS-9064) NN old UI (block_info_xml) not available in 2.7.x
Date Tue, 22 Sep 2015 14:03:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14902678#comment-14902678

Rushabh S Shah commented on HDFS-9064:
--------------------------------------

[~kanaka]: Thanks for taking up the jira.
bq. I think get block info feature can be provided back through webhdfs GET request.
For querying via webhdfs, this requires the browser to be authenticated via SPNEGO.
This was not the case with block_info_xml.jsp utility in 2.6.

If webhdfs (which requires SPNEGO authentication) is the only way to implement this feature,
then we already have an alternative to use fsck command 
{noformat}
hdfs fsck  -blockId blk_xxx
{noformat}

bq. If fine, I will go a head to implement the same.
 If other people in the community are interested in this feature, then you can go ahead and
implement.

>             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.
