Subject [jira] Commented: (HADOOP-6708) New file format for very large records
Date Fri, 16 Apr 2010 21:43:26 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12858015#action_12858015

Aaron Kimball commented on HADOOP-6708:
---------------------------------------

I'm definitely able to help test. I can do some manual testing of large records / performance
after there's a patch available.

I wasn't suggesting that we use CountingInputStream in there; I was mostly using that as an
example of having dual interfaces to retrieve the same value -- one as an integer ({{getCount()}}),
and the other as a long ({{getByteCount()}}). This is not my preference; I'd prefer to modify
the existing methods. But it is an incompatible change, so I figured I'd check first.
