> Project: Hadoop HDFS

> Components: hdfs-client
> Affects Versions: 2.6.0
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Fix For: 2.7.0

>
> HDFS should have a debug command which could validate HDFS block files, call
> recoverLease, and have some other functionality. These commands would be
> purely for debugging and would appear under a separate command hierarchy
> inside the hdfs command. There would be no guarantee of API stability for
> these commands and the debug submenu would not be listed by just typing the
> "hdfs" command.
