Not sure what you meant by deleting bloom filter type.
Bloom filter type is used when constructing store file. See the following
in HStore:
private HStoreFile createStoreFileAndReader(StoreFileInfo info) throws
IOException {
info.setRegionCoprocessorHost(this.region.getCoprocessorHost());
HStoreFile storeFile = new HStoreFile(this.getFileSystem(), info, this.
conf, this.cacheConf,
this.family.getBloomFilterType(), isPrimaryReplicaStore());
If you want to use a different bloom filter, you can issue this command:
alter 'test', { NAME => 'cf', BLOOMFILTER => 'ROW' }
Cheers
