Hdfs Federation: Add command to delete block pool directories from a datanode.
------------------------------------------------------------------------------
Key: HDFS-1791
URL: https://issues.apache.org/jira/browse/HDFS-1791
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: Federation Branch
Reporter: Jitendra Nath Pandey
Assignee: Jitendra Nath Pandey
Fix For: Federation Branch
A command to delete block pool directories from the datanode is required. Once
a datanode stops serving a block pool, this command can be used to delete the
block pool directories. A force option will delete the block pool directory on
the datanode along with all its contents. If force is not specified directories
will be deleted only if no block files exist for that block pool.
