>
> Currently it is possible to enable a bloom filter after a table is created 
> and data has been stored in it by disabling the table and modifying the 
> column.
> While this correctly sets the attribute in the column descriptor, it does not 
> create bloom filters for existing data so that on the first compaction, an 
> NPE will be thrown because the HStore expects each HStoreFile to have a bloom 
> filter.
