Subject [jira] Commented: (PIG-1158) pig command line -M option doesn't support table union correctly (comma seperated paths)
Date Fri, 18 Dec 2009 19:14:18 GMT

    [ https://issues.apache.org/jira/browse/PIG-1158?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12792589#action_12792589
] 

Richard Ding commented on PIG-1158:
-----------------------------------

Without -M option Pig converts paths to their absolute locations before passing them to the
loaders/storers. With -M option, Pig passes the paths "as is" to the loaders/storers. 

This distinction seems to be obsolete. The fix will be to convert paths to their absolute
locations in both cases.
