Subject Running java stress tests
Date Mon, 07 Nov 2011 03:15:13 GMT
Hi,

I am attempting to run the java stress tests:

Tests to the local machine work fine:

# sh stress -d localhost -n 1000000

Unable to create stress keyspace: Keyspace names must be case-insensitively
unique
total,interval_op_rate,interval_key_rate,avg_latency,elapsed_time
321975,32197,32197,0.0011982358878794939,10
608889,28691,28691,0.0014594442934119632,20
897246,28835,28835,0.0014675003554621528,30

......


9894395,11904,11904,0.002851321382369248,505
10000000,10560,10560,0.003761071918943232,513
END

Tests to a number of the remote machines do not:


# sh stress -d 10.1.255.254 -n 10000000


Exception in thread "main" java.lang.RuntimeException:
java.net.ConnectException: Connection refused
at org.apache.cassandra.stress.Session.getClient(Unknown Source)
 at org.apache.cassandra.stress.Session.createKeySpaces(Unknown Source)
at org.apache.cassandra.stress.StressAction.run(Unknown Source)
 at org.apache.cassandra.stress.Stress.main(Unknown Source)


This is without firewalls, on the same private subnet with DNS resolvings
hostname correctly. Nothing shows up in the cassandra logs on either the
machine where the stress test command was invoked or where it was intended
to run.

Has anyone seen this problem before?

Thanks,

Joe
