Subject [jira] [Commented] (HBASE-5304) Pluggable split key policy
Date Wed, 01 Feb 2012 03:02:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13197537#comment-13197537
] 

Zhihong Yu commented on HBASE-5304:
-----------------------------------

Since there is a chance that SplitKeyPolicy may decide not to split, I think the following
code should be prepared:
{code}
+      SplitTransaction st = new SplitTransaction(parent, parent
+          .getSplitKeyPolicy().getSplitKey(parent, midKey));
{code}
Meaning, we should check whether a SplitTransaction is needed.
