> 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.
