      Description

      hbase:meta is currently hardcoded. Its schema cannot be change.

      This issue is about allowing edits to hbase:meta schema. It will allow our being able to set encodings such as the block-with-indexes which will help quell CPU usage on host carrying hbase:meta. A dynamic hbase:meta is first step on road to being able to split meta.
