[jira] [Commented] (HBASE-4021) Further parallelize HMaster.createTable()

    [ https://issues.apache.org/jira/browse/HBASE-4021?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13067676#comment-13067676 ] 

Harsh J commented on HBASE-4021:
--------------------------------

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.

> 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.
