stack commented on HADOOP-1550:
-------------------------------
After playing in HADOOP-1784, here's some thoughts on this issue.
HADOOP-1784 added deleteAll. It takes a timestamp and a column name.
Internally it asks a new getKeys method for a list of all keys that match the
passed column and that are older than or equal to the passed timestamp.
To delete a whole row, we could add a deleteAll that just took a timestamp and
a version of getKeys that returned all entries on a row -- not just all entries
in a row that match the passed column. This new deleteAll would then work like
the current deleteAll adding a delete cell for every key returned by the
getKeys call.
Deleting all members of a column family would be a matter of removing all store
files under the column family HStore (and any matching entries in memcache).

> Project: Hadoop
> Issue Type: Bug
> Components: contrib/hbase
> Reporter: stack
> Priority: Minor
>
> There is no support in hbase currently for deleting a row -- i.e. remove all
> columns and their versions keyed by a particular row id. Nor is there a
> means of passing in a row id and column family name having hbase delete all
> members of the column family (for the designated row).
