["Liang Xie (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-9894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13813824#comment-13813824 ] 

Liang Xie commented on HBASE-9894:
----------------------------------

HBase version:  0.94.6-cdh4.3.0

java -version：
 
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

export HBASE_OPTS="-ea -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode"

To me, that assert statement in getSplitPoint() is inappropriate, and in trunk code, it has been removed already, let's just make a one line remove here, is that OK? [~lhofhansl]
