I think the the semicolon should be at line #25 instead of #23.
Updated to reflect profile changes in 2.1.1
The tool looks awesone but my company uses "map < text , text >" type in the schema.
How much effort would be needed to add support for this type?
Where the changes need to be made?
Is it something that junior developer can handle?
I'm getting an error when I try to run cassandra-stress. I downloaded the source code and built it today using ant 1.9.4.
Command> infomav:tools infomav:tools$ ./bin/cassandra-stress user profile=blogpost.yaml ops(singlepost=1)
Error> Error: Could not find or load main class org.apache.cassandra.stress.Stress
How to fix this?
Found the issue. I was using build instead of release command in Ant. This caused it to skip creation of the JAR files and binary tar files.
Once I changed commands, I found the correct tar archive (bin.tar.gz) in build folder and was able to unpack and use it to run cassandra-stress.
When I make the below changes:
- name: published_date
cluster: fixed(100)
select: fixed(1)/100
I am seeing very different results. ( very high opcounts/rowcounts/pk counts and better mean latencies)
Some how it appears to me the tools itself is causing the delay when it generates the rows when the cluster: fixed values are high.
How can I set the write consistency level for running cassandra stress test?
cl= gives the ability to set read/write consistency level, for example:
cassandra-stress write cl=QUORUM -schema 'replication(factor=3)'
Hi,
I am trying to pass request_trace.yaml as an input to the stress-tool as below:
./cassandra-stress user profile=request_trace.yaml n=1000000 ops(likelyquery0=1,likelyquery1=2,insert=1) -node 10.32.100.16
the script is perfectly working fine for the other tables. But I get the below error for request_trace table. Please check the request_trace.yaml file for the script.
Can someone suggest a solution for this?

I am planning on using this tool. So if I give a query like "SELECT * FROM user where id = ? and name = ?" How do I pass the values for id and name for the load tests. Or does this tool automatically use the values in the table?
