["Frank Chang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-13347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14984355#comment-14984355 ] 

Frank Chang commented on HBASE-13347:
-------------------------------------

I'm tried to use https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/mapreduce/RowCounter.java code and package a new jar then excuted following shell script:
{code:none}
hadoop jar test.jar <tablename> --range=row001,row002 cf:c2
{code}
Then I got "NoSuchColumnFamilyException".

Is that normally? 
And I tried to add 
{code:java}
continue; 
{code}
after #L123 to avoid "--range=*" string be appended to qualifer.

Then the problem seems solve.

data in table:
||row||cf:c1||cf:c2||cf:c3||cf:c4||
|row001|v1|v2| | |
|row002| |v2|v3| |
|row003| | |v3|v4|
|row004|v1| | |v4|

> The {{RowCounter}} in the {{mapreduce}} package is supposed to check if the row count scan has a column selection added to it, and if so, use a different filter that finds the row and counts it. But the {{qualifier.add()}} call is missing in the {{for}} loop. See https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/mapreduce/RowCounter.java#L165
> Needs fixing or row count might be wrong when using {{--range}}.
