Commented: (PIG-1124) Unable to set Custom Job Name using the -Dmapred.job.name parameter


    [
https://issues.apache.org/jira/browse/PIG-1124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12828005#action_12828005

Ashutosh Chauhan commented on PIG-1124:
---------------------------------------

Thanks for the review, Dmitriy. 
AFAIK, there aint any other property that Pig overrides such that user can't set it himself using -D switch.
Correct me if I am wrong. job.name was special-cased so that if user doesnt provide job name, pig sets the
name itself to make it easy to track jobs submitted by pig on the cluster.  Bug in this ticket is Pig was always
setting the name(instead of setting only when user wasnt supplying any), thus completely ignoring user
supplied name through -D switch.

---------------------------------

-1.  The original intent of the JIRA was to move from double quotes to single, to match the rest of string usage
in the language.  Further discussion is needed if we want to move these to identifiers instead.
