Chia-Ping Tsai commented on HBASE-18142:
----------------------------------------
bq. could this be the reason we are deleting all the versions of all the cells
in that row?
Not exactly. The _deleterows_internal call _createdelete_internal for getting
the Delete object. The _createdelete_internal create the Delete object through
[Delete#addColumns|https://github.com/apache/hbase/blob/master/hbase-client/src/main/java/org/apache/hadoop/hbase/client/Delete.java#L258].
The purpose of the Delete#addColumns is to *delete all versions of the
specified column with a timestamp less than or equal to the specified
timestamp*.
> Deletion of a cell deletes the previous versions too

> Project: HBase
> Issue Type: Bug
> Components: API
> Reporter: Karthick
> Labels: beginner
>
> 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.

> 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.
