Subject [jira] [Commented] (HBASE-7876) Got exception when manually triggers a split on an empty region
Date Wed, 27 Feb 2013 08:51:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7876?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13588127#comment-13588127

clockfly commented on HBASE-7876:
---------------------------------

I think there are several motives:
1. HBaseAdmin can allow splitting by specifying a midkey. For a empty region, we should allow
the user to manual split a empty region if the user expects there will be heavy load for this
region future.
2. We allow user to customize the SplitPolicy, the splitpoint can be customized. When the
customized SplitPolicy said that we need split at xx point, then we should support it, no
matter there is store files in the region or not.
