Russ Hatch created CASSANDRA-6883:
-------------------------------------
Summary: stress fails with IOException "Data returned was not
validated" on read
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...
