Description

After upgrading one node from 1.2 to 2.0, the following query fails with timeout:

Connected to test at localhost:9160.
[cqlsh 4.1.0 | Cassandra 2.0.5.1-SNAPSHOT | CQL spec 3.1.1 | Thrift protocol 19.39.0]
Use HELP for help.
cqlsh> select count(*) from cfs.sblocks;
Request did not complete within rpc_timeout.

Table definition:

cqlsh> describe columnfamily cfs.sblocks;

CREATE TABLE sblocks (
  key blob,
  column1 blob,
  value blob,
  PRIMARY KEY (key, column1)
) WITH COMPACT STORAGE AND
  bloom_filter_fp_chance=0.000068 AND
  caching='KEYS_ONLY' AND
  comment='Stores blocks of information associated with a inode' AND

The 1.2 node reports the following error:
