Subject [jira] Commented: (CHUKWA-578) Empty row key injected into HBase
Date Sat, 08 Jan 2011 20:48:45 GMT

    [ https://issues.apache.org/jira/browse/CHUKWA-578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12979198#action_12979198

Eric Yang commented on CHUKWA-578:
----------------------------------

Additional testing on Chukwa, there is no empty row key getting injected into hbase.  My previous
testing method was flawed.

Try this on hbase shell:

hbase(main):066:0> put 'HadoopLog', 'test', 'Audit:this', '1' 
0 row(s) in 0.0080 seconds
hbase(main):070:0> get 'HadoopLog',''                                         
COLUMN                       CELL                                                        
                    
 Audit:this                  timestamp=1294519094575, value=1                            
                    
1 row(s) in 0.0070 seconds

The row key is test, but when getting without a row key specified, it will give all columns,
it's a good way to find all columns in a table.  Hence, this bug is invalid.
