- You should be using 0.92.0 if you want to mess w/ blooms I'd say.

I am using the version right before that (I think -- somewhat new to
hbase) -- it's the cloudera distro: hbase-0.90.4-cdh3u2.
Figured bloom filters were an option, since it lists
BLOOMFILTER=>'NONE' as the attribute now. This is the command I'm
trying to do (after disabling the table):
hbase(main):013:0> alter 'ExistenceTable', METHOD => 'table_att',
hbase(main):014:0* BLOOMFILTER => 'ROW'
0 row(s) in 0.1360 seconds
hbase(main):015:0> describe 'ExistenceTable'
DESCRIPTION ENABLED
{NAME => 'ExistenceTable', FAMILIES => [{NAME => 'I false

Unfortunatlye, it still says BLOOMFILTER => 'NONE'.
Any thoughts?
Thanks,
Ben
