Subject [jira] Commented: (MAPREDUCE-2046) A input split cannot be less than a dfs block

Owen O'Malley commented on MAPREDUCE-2046:
------------------------------------------

Ah. I don't know that one. If you want to reopen the bug for that specific input format, that
would make sense.

> I ran into this while testing some hive features.
> Whether we use hiveinputformat or combinehiveinputformat, a split cannot be less than
a dfs block size.
> This is a problem if we want to increase the block size for older data to reduce memory
consumption for the
> name node.
> It would be useful if the input split was independent of the dfs block size.
