Zhihong Ted Yu commented on HBASE-6564:
---------------------------------------

@J:
If you look at patch v2 closely, you can see that it is composed of two patch 
files (line 310).

I suggest renaming TestTableFamilyHandlers.java -> 
TestTableDeleteFamilyHandler.java because only TableDeleteFamilyHandler is 
tested.
There're a lot of two (successive) empty lines in this new file.
Please remove redundant empty line.

 * Copyright 2009 The Apache Software Foundation
{code}
The above line should be removed from license header.
{code}
   // 4 - Check if all the 3 column families exists in FS
{code}
'exists' -> 'exist'
{code}
  public org.apache.hadoop.hbase.ResourceCheckerJUnitRule cu = new 
org.apache.hadoop.hbase.ResourceCheckerJUnitRule();
{code}
The above line is longer than 100 characters. Please wrap.

Please regenerate patch and attach to this JIRA.

Thanks
