Components: Tools
Affects Versions: 1.2.1
Environment: DataStax community AMI
Reporter: chris erway
Priority: Minor
Tried to import some JSON tables using json2sstable today on a new cluster
using the Murmur3Partitioner. It threw this exception:
$ sudo -u cassandra json2sstable -K Keyspace -c CFName
Keyspace-CFName-hd-1-Data.db.json Keyspace-CFName-hd-1-Data.db
log4j:WARN No appenders could be found for logger
(org.apache.cassandra.config.DatabaseDescriptor).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more
info.

ERROR: org.apache.cassandra.utils.Murmur3BloomFilter cannot be cast to

There's a related issue in CASSANDRA-4196 having to do with bulk loading that
suggests a fix might involve passing the right type down to the FilterFactory
(?)
