dhruba borthakur commented on HDFS-222:
---------------------------------------
This is a useful feature to have. I am guessing that there will be a few more
hdfs-specific tools that we will develop going forward. This toll currently is
invoked by "bin/hadoop jar org.apache.hdfs.tools.HDFSConcat fileA fileB". Does
it make it easier to use if this can be "bin/hadoop hdfs -concat fileA fileB"?
