Description

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 addColumn(final byte [] family, final byte [] qualifier, final long timestamp)) only deletes the current version of the cell. The previous versions are not deleted.
