[ http://issues.apache.org/jira/browse/HADOOP-454?page=comments#action_12457933 ]
Hairong Kuang commented on HADOOP-454:
--------------------------------------
I plan to solve the problem by introducing a new command "dus", which prints the total disk
usage for each argument. This solution is aligned to what we have in the dfs shell: "lsr"
for "ls -r" and "rmr" for "rm -r".
A better and a long term solution is to allow options for dfs commands, i.e., supporting "du
-s" instead of "dus". But we need to enhance dfs command arguments parsing to handle options.
Something like common-cli is a good choice.
> hadoop du optionally behave like unix's du -s

> Key: HADOOP-454
> URL: http://issues.apache.org/jira/browse/HADOOP-454
> Project: Hadoop
> Issue Type: New Feature
> Components: dfs
> Affects Versions: 0.5.0
> Reporter: Marco Nicosia
> Assigned To: Hairong Kuang
> Priority: Trivial
>
> In Unix, the user has the option to specify a -s flag:
> -s Display an entry for each specified file. (Equivalent to -d 0)
> Instead of providing data for the subdirectories of the arguments, du prints the total
usage of each argument, without printing subdirectories.
> This is very convenient for those looking to find how much space is used by a particular
branch, without requring them to add up all the sub-usages.
