----------------------------------------

Please fix the warnings.

{code}
-      @test_table.delete(103, "x:a")
+      @test_table.delete(103, 'x:a')
       res = @test_table._get_internal('103', 'x:a')
-      assert_nil(res)
+      assert_not_nil(res)
{code}
Consider checking the content of returned cells

> When I tried to delete a cell using it's timestamp in the Hbase Shell, the previous versions
of the same cell also got deleted. But when I tried the same using the Java API, then the
previous versions are not deleted and I can retrive the previous values.
> https://github.com/apache/hbase/blob/master/hbase-client/src/main/java/org/apache/hadoop/hbase/client/Delete.java
> see this file to fix the issue. This method (public Delete addColumns(final byte [] family,
final byte [] qualifier, final long timestamp)) only deletes the current version of the cell.
The previous versions are not deleted.
