[ 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.
