RE: FW: Deletes not commiting from custom java API but work in shell interface

[Bell, Philip S CIV SPAWARSYSCEN-PACIFIC, 81320]

Ah I forgot to clean up my testing code, when I saw deletes weren't working I 
tried setting it to the last version timestamp to see if it required an exact 
match.

So no matter if I submit 
delMutation.putDelete( colFam, colQual, new ColumnVisibility( colVis ), 
e.getKey().getTimestamp() );

or

delMutation.putDelete( colFam, colQual, new ColumnVisibility( colVis ) );

I am still seeing the entries I wanted to delete

Deletes will remove all entries which occur before the key. I believe there is 
undefined behavior for when a delete key is identical. It should work if you 
set the delete keys time +1.

        Using the following code, rows are never deleted even when identified 
and submitted for deletion to the batchwriter.
        After running the code the rows still show up in search.
        
        This has been seen in 1.4.1 and 1.4.2
        
        The same rows can be deleted from the accumulo shell interface
