Subject [jira] Commented: (HADOOP-3315) New binary file format
Date Tue, 09 Sep 2008 05:21:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12629393#action_12629393

If that is the case, are you planing to provide an API to get the total number of rows in
a directory when all files in the directory are TFiles ?

> SequenceFile's block compression format is too complex and requires 4 codecs to compress
or decompress. It would be good to have a file format that only needs
