Subject [jira] [Created] (CASSANDRA-6074) Read regression in 2.0.1
Date Sat, 21 Sep 2013 00:18:52 GMT
Ryan McGuire created CASSANDRA-6074:

             Summary: Read regression in 2.0.1
                 Key: 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.

 * 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:

!stress 2.0.0 vs 2.0.01.png!

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