    Description

      This is from the user list as reported by Anoop Sharma

       running into an issue related to visibility expressions and delete.
      Example run from hbase shell is listed below.
      Will appreciate any help on this issue.
      thanks.
      In the example below, user running queries has ‘MANAGER’ authorization.
      *First example:*
      
        add a column with visib expr ‘MANAGER’
      
        delete it by passing in visibility of ‘MANAGER’
        This works and scan doesn’t return anything.
      *Second example:*
      
        add a column with visib expr ‘MANAGER’
      
        delete it by not passing in any visibility.
        This doesn’t delete the column.
        Scan doesn’t return the row but RAW scan shows the column
        marked as deleteColumn.
        Now if delete is done again with visibility of ‘MANAGER’,
        it still doesn’t delete it and scan returns the original column.
      
      *Example 1:*
      hbase(main):096:0> create 'HBT1', 'cf'
      hbase(main):098:0* *put 'HBT1', 'John', 'cf:a', 'CA',
      {VISIBILITY=>'MANAGER'}*
      hbase(main):099:0> *scan 'HBT1'*
      ROW
      COLUMN+CELL
      
       John                 column=cf:a, timestamp=1446154722055,
      value=CA
      1 row(s) in 0.0030 seconds
      hbase(main):100:0> *delete 'HBT1', 'John', 'cf:a', {VISIBILITY=>'MANAGER'}*
      0 row(s) in 0.0030 seconds
      
      hbase(main):101:0> *scan 'HBT1'*
      ROW
      COLUMN+CELL
      0 row(s) in 0.0030 seconds
      
      *Example 2:*
      
      hbase(main):010:0* *put 'HBT1', 'John', 'cf:a', 'CA',
      {VISIBILITY=>'MANAGER'}*
      0 row(s) in 0.0040 seconds
      
      hbase(main):011:0> *scan 'HBT1'*
