HMaster.createTable could be heavily optimized
----------------------------------------------
Key: HBASE-4010
URL: https://issues.apache.org/jira/browse/HBASE-4010
Project: HBase
Issue Type: Improvement
Affects Versions: 0.90.3
Reporter: Jean-Daniel Cryans
Fix For: 0.92.0
Looking at the createTable method in HMaster (the one that's private), we seem
to be very inefficient:
- We set the enabled flag for the table for every region (should be done only
once).
- Every time we create a new region we create a new HLog and then close it
(reuse one instead or see if it's really necessary).
- We do one RPC to .META. per region (we should batch put).
This should provide drastic speedups even for those creating tables with just
50 regions.
