[jira] Commented: (HADOOP-5266) Values Iterator should support "mark" and "reset"

    [ https://issues.apache.org/jira/browse/HADOOP-5266?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12689749#action_12689749 ] 

Owen O'Malley commented on HADOOP-5266:
---------------------------------------

This shouldn't be done for the old api. It should only be done on the mapreduce api.

> Some users have expressed interest in having a mark-reset functionality on values iterator. Users can call mark() at any point during the iteration process and a subsequent reset() should move the iterator to the last value emitted when mark() was called.
