Anoop Sam John commented on HBASE-18142:
----------------------------------------
The description says
bq.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.
But that is not correct. addColumn (Pls see there is no 's') is what delete
exactly one version.
> Deletion of a cell deletes the previous versions too

> 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.
