Subject [jira] [Commented] (HBASE-6336) Split point should not be equal with start row or end row
Date Mon, 09 Jul 2012 01:57:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13409121#comment-13409121

chunhui shen commented on HBASE-6336:
-------------------------------------

@ram
In current logic, if no kvs in one region, we will failed getting split point because following
code when call StoreFile.Reader.midkey()
{code}
if (rootCount == 0)
        throw new IOException("HFile empty");
{code}

Do you mean allow to get split point for the above case? Or other?

We will catch above IOException and return null for getSplitPoint, I think it is ok...
