Remove HTableDescriptor from HRegionInfo
----------------------------------------
Key: HBASE-451
URL: https://issues.apache.org/jira/browse/HBASE-451
Project: Hadoop HBase
Issue Type: Improvement
Affects Versions: 0.2.0
Reporter: Jim Kellerman
Priority: Minor
There is an HRegionInfo for every region in HBase. Currently HRegionInfo also
contains the HTableDescriptor (the schema). That means we store the schema n
times where n is the number of regions in the table.
Additionally, for every region of the same table that the region server has
open, there is a copy of the schema. Thus it is stored in memory once for each
open region.
If HRegionInfo merely contained the table name the HTableDescriptor could be
stored in a separate file and easily found.
