[jira] Commented: (HADOOP-222) Set replication from dfsshell

    [ http://issues.apache.org/jira/browse/HADOOP-222?page=comments#action_12412249 ] 

Konstantin Shvachko commented on HADOOP-222:
--------------------------------------------

This is very useful.
Some things that I have noticed.
- Usage info might be useful.
Right now it just throws ArrayIndexOutOfBoundsException if you do not specify the path.
Or some other exception if you forget to provide the replication number. Try
    hadoop dfs -setrep
    hadoop dfs -setrep 3
    hadoop dfs -setrep /user
- I think the 2 commands should be combined into one like
    hadoop dfs -setrep [-R] <path>
- Should we use abbreviations like "setrep" or full names?
see HADOOP-226 (4) about necessity for a general DFSShell convention.
