Subject Exceptions on 0.7.0
Date Wed, 09 Feb 2011 20:05:46 GMT
I have a 4 node test cluster were I test the port to 0.7.0 from 0.6.X
On 3 out of the 4 nodes I get exceptions in the log.
I am using RP.
Changes that I did:
1. changed the replication factor from 3 to 4
2. configured the nodes to use Dynamic Snitch
3. RR of 0.33

I run repair on 2 nodes  before I noticed the errors. One of them is having
the first error and the other the second.
I restart the nodes but I still get the exceptions.

The following Exception I get from 2 nodes:
 WARN [CompactionExecutor:1] 2011-02-09 19:50:51,281 BloomFilter.java (line
84) Cannot provide an optimal Bloom
Filter for 1986622313 elements (1/4 buckets per element).

On another node I get:
