[jira] [Commented] (MAHOUT-842) Inconsistent and conflicting use of '-i' flag

["Hudson (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAHOUT-842?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13128316#comment-13128316 ] 

Hudson commented on MAHOUT-842:
-------------------------------

Integrated in Mahout-Quality #1096 (See [https://builds.apache.org/job/Mahout-Quality/1096/])
    MAHOUT-842 test pass, no objections heard. If it creates any breakage in scripts, it will be minor and self-explanatory and better to standardize now

> As the Cloudera folk noted on the mailing list, the "-i" option doesn't work for "--input" on RecommenderJob as the job actually overwrites "-i" to mean something else. We can fix that by removing the short name for this option. And removing similarly conflicting short names elsewhere.
> Along the way I noticed how much code doesn't use standard input/output flags. I've tried to standardize as much of that as possible.
