[jira] [Created] (HBASE-4021) Further parallelize
HMaster.createTable()
Further parallelize HMaster.createTable()
-----------------------------------------
Key: HBASE-4021
URL: https://issues.apache.org/jira/browse/HBASE-4021
Project: HBase
Issue Type: Improvement
Reporter: Ted Yu
HBASE-4010 paved the way for further speedup in HMaster.createTable().
Namely, the creation of HRegions should be performed using ExecutorService if the number of regions cross certain threshold.

--------------------------------
Ted,
I was thinking of starting this up. Reading through HBASE-4010, I notice that you may have had a WIP patch that parallelizes the region creation for performance. If you could attach that here I can start with that, or I can start from scratch if its been lost/unavailable.

@Harsh:
I haven't started this part of work yet.
Thanks for following up.
You may need to perform some trials to find out the proper threshold and see how much performance gain can be achieved.
