Aaron T. Myers commented on HDFS-6663:
--------------------------------------
Hey Kihwal, can't this be done currently by doing something like this?
{code}
hdfs fsck / -files -blocks -locations | grep <block ID>
{code}
> Admin command to track file and locations from block id

> Key: HDFS-6663

> Project: Hadoop HDFS
> Issue Type: New Feature
> Reporter: Kihwal Lee
> Assignee: Chen He
>
> A dfsadmin command that allows finding out the file and the locations given a
> block number will be very useful in debugging production issues. It may be
> possible to add this feature to Fsck, instead of creating a new command.
