> Key: CASSANDRA-6883
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6883
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Environment: ccm 3 node cluster, java 1.7.0_51
> cassandra 2.1 branch -- 615612f61566
> Reporter: Russ Hatch
>
> I'm working to do some basic testing of read/write with the new stress.
> First, I populate data using write like so:
> {noformat}
> rhatch@whatup:~/git/cstar/cassandra$ tools/bin/cassandra-stress write
> n=1000000 CL=ONE -key dist=FIXED\(1\) -col n=UNIFORM\(1..100\) -schema
> replication\(factor=3\) -rate threads=50
> {noformat}
> Then I attempt a read test, and this happens:
> {noformat}
> rhatch@whatup:~/git/cstar/cassandra$ tools/bin/cassandra-stress read
> n=1000000 CL=ONE -key dist=FIXED\(1\) -col n=UNIFORM\(1..100\) -schema
> replication\(factor=3\) -rate threads=50
> Warming up READ with 50000 iterations...
