Bryan Duxbury commented on HBASE-451:
-------------------------------------
I like that idea because then we don't have to work very hard to store that
information. It also means we can check if a table exists by doing a single
get, instead of a META scan. We can also quickly tell if META is corrupt
because we have a reliable place to find table names.
All in all, +1 to that idea.
> 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.
