Haohui Mai commented on HDFS-9064:
----------------------------------
HDFS-8246 has discussions on the same topic. My understanding is that the
conclusion is that the information is not fully accurate and fsck is able to
solve the use case. Thus IMO we should leave it out.
> NN old UI (block_info_xml) not available in 2.7.x

>
> Key: HDFS-9064
> 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.
