Subject [jira] Commented: (MAPREDUCE-767) to remove mapreduce dependency on commons-cli2
Date Thu, 20 Aug 2009 16:44:15 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745487#action_12745487
] 

Amar Kamat commented on MAPREDUCE-767:
--------------------------------------

>From the documentation of [cli2|http://commons.apache.org/sandbox/cli2/] and [cli1.2|http://commons.apache.org/cli/release_1_2.html],
its clear that cli1.2 doesnt support [Validators|http://commons.apache.org/sandbox/cli2/manual/validators.html]
and [PropertyOption|http://commons.apache.org/sandbox/cli2/manual/options.html]. But from
my manual testing it seems like we can have a workaround for that. Options like _-jobconf_
and _-cmdenv_ extend PropertyOption. Also _-file_ option uses Validators which can be checked
once the option is parsed. I didnt see any difference in streaming command-line parsing with
the patch.
