Date Sat, 04 Aug 2012 01:51:02 GMT

Enis Soztutar updated HBASE-6052:
---------------------------------

    Attachment: HBASE-6052_v1.patch

Uploaded a patch to https://reviews.apache.org/r/6327/diff/#index_header.

Changes HRegionInfo serialization in META and ROOT from Writable to PB. 

The first version of the patch: 
 - converts references for HRegionInfo serialization into PB
 - changes most of the code paths that does META operations into using MetaEditor and MetaReader
methods. 
 - Support migration from 0.92 and 0.94 to 0.96. Migration code is adapted from the 0.90->0.92
migration code.
 - Remove classes supporting 0.90 -> 0.92 migration. HRegionInfo090x, MetaMigrationRemovingHTD,
etc
 - Changes ruby shell to use new serialization 

NOTE: 
 - META table contains info:server and info:startCode as String and int serialized with Bytes.toBytes().
Those are not converted to PB structures.
