Jothi Padmanabhan updated HADOOP-5266:
--------------------------------------
Attachment: hadoop-5266-v2.patch
New patch incorporating review comments. Made some additional changes based on
offline comments from Devaraj and Owen. Some points:
# Functionality is supported only for the new API
# User creates a MarkableIterator that takes the original iterator in its
constructor. See TestValueIterReset.java
# Even though the functionality is supported only for new API, BackupStore.java
is in mapred package as it access IFile and Merger.Segment which are package
private
> Values Iterator should support "mark" and "reset"

> 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.
