[jira] [Commented] (HBASE-10026) HBaseAdmin#createTable could fail if region splits too fast

["Matteo Bertozzi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-10026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13831982#comment-13831982 ] 

Matteo Bertozzi commented on HBASE-10026:
-----------------------------------------

looks good to me, since at the moment there is no automatic region remove/merge.
(thinking at the snapshot case where your create table has already some data in it)
