Subject [jira] [Commented] (PIG-3257) Add unique identifier UDF
Date Tue, 28 May 2013 20:19:20 GMT

    [ https://issues.apache.org/jira/browse/PIG-3257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13668630#comment-13668630
] 

Koji Noguchi commented on PIG-3257:
-----------------------------------

Would this ensure that same unique identifier is reproduced when (map) task attempt is retried?
 Otherwise, I'm afraid it would lead to a random pig behavior when we use this id as the map-reduce
key.
