Description

Change MultiHFileOutputFormat to MultiTableHFileOutputFormat, Continuing work to enhance the MultiTableHFileOutputFormat to make it more usable:

MultiTableHFileOutputFormat follow HFileOutputFormat2
(1) HFileOutputFormat2 can read one table's region split keys. and then output multiple hfiles for one family, and each hfile map to one region. We can add partitioner in MultiTableHFileOutputFormat to make it support this feature.

(2) HFileOutputFormat2 support Customized Compression algorithm for column family and BloomFilter, also support customized DataBlockEncoding for the output hfiles. We can also make MultiTableHFileOutputFormat to support these features.
