Subject [jira] [Updated] (HDFS-6521) Improve the readability of 'hadoop fs -help'
Date Thu, 12 Jun 2014 22:44:01 GMT

Lei Xu updated HDFS-6521:

    Attachment: HDFS-6521.003.patch

Thanks [~clamb] for the quick review! It seems that I'd set my IDE to disallow it to automatically
trim the spaces. 

Here is the new patch that addresses your comments. Additionally, it fixed a bug that the
original code used {{System.out}} instead the {{out}} parameter, which is usually {{System.err}},
 to print messages.

[~andrew.wang], could you please do another round of review for me?
