[jira] [Closed] (HBASE-6278) Allow table splits during a MapReduce job to be parameterized the same way as we parameterize the splitAlgorithm during table creation.

> Current implementation uses Uniform Splits, which can be different from the one used to create the table (if created using HexSplit).
> Using different split algorithms results in input splits that are skewed. Allow the MR job to accept a split Algorithm to enable even splitting into map tasks.
