Subject BloomFilterFalsePositives equals 1.0
Date Wed, 22 Jun 2011 03:06:56 GMT
     I have a problem with bloom filter. When made a test which tried to get
some nonexistent keys, it seemed that the bloom filter does not work. The
'BloomFilterFalseRatio' was 1.0 and the 'BloomFilterFalsePositives' was
rising and the disk I/O utils reached 100% according to 'iostat'.

    I found the patch in , but in my cluster key
cache had been enabled already.  My Cassandra version is 0.7.3. There are 3
nodes and RF is 3.

    Thanks for your help.
