Subject Re: whats the default .yaml file that cassandra-stress uses
Date Thu, 07 Jul 2016 10:33:46 GMT
I added

concurrent_writes: 48

to the cqlstress-example.yaml, which is recommended as No. of cores * 8.
But no improvement is made when trying 1000000 writes test.

Since cassandra.yaml specifies concurrent_writes, but cqlstress-example.yaml
doesn't.

BTW, the following warning was shown as the first line of the test.

WARN  10:25:44 You listed localhost/0:0:0:0:0:0:0:1:9042 in your contact
points, but it wasn't found in the control host's system.peers at startup

how to fix it?

many thanks
