I have a HBase table with a single column family and columns are added to it over time. These columns are named as the timestamp they were created, so unless I query the row I do not know what all columns it has.
Now given a row, I want to _atomically_ remove all the existing columns of this column family and add a new set of columns and values. So I thought of using RowMutations like: ============== RowMutations mutations = new RowMutations(row); //delete the column family Delete delete = new Delete(row); delete.deleteFamily(cf); //add new columns Put put = new Put(row); put.add(cf, col1, v1); put.add(cf, col2, v2); //delete column family and add new columns to same family mutations.add(delete); mutations.add(put); table.mutateRow(mutations); ============== But what this code ends up doing is just deleting the column family, it does not add the new columns. Is this behaviour expected? If so, then how can I achieve my goal of _atomically_ replacing all columns of a column family with a new set of columns? Thanks, Vinod
