Subject Re: Delete multiple records column family for particular rowkey of hbase table
Date Wed, 11 Feb 2015 17:55:43 GMT
So you want to just delete all the rows in a column family and you don't
want to specify the rowkeys.
You can try BulkDeleteEndPoint. It allows the user to specify a scan based
on which the delete can be executed.
