---------------------------------------
Summary: Read regression in 2.0.1
Key: CASSANDRA-6074
URL: https://issues.apache.org/jira/browse/CASSANDRA-6074
Project: Cassandra
Issue Type: Bug
Reporter: Ryan McGuire
Attachments: stress 2.0.0 vs 2.0.01.png
I'm seeing a regression in stress reads introduced in 2.0.1.
Setup
* 4 node cluster using default settings
* Write: -F 30000000 -n 30000000 -i 5 -l 2
* Read: -n 30000000 -o read -i 5
I tried this three times on 2.0.0 and on 2.0.1(tentative; eb96db6c)
2.0.0 is fine, but 2.0.1 timed out of it's read 2 out of the 3 times:

I will bisect and update this when I find the commit that introduced this.
