[jira] [Created] (CASSANDRA-8429) Stress on trunk fails mixed workload on missing keys

Ariel Weisberg created CASSANDRA-8429:
-----------------------------------------

             Summary: Stress on trunk fails mixed workload on missing keys
                 Key: CASSANDRA-8429
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8429
             Project: Cassandra
          Issue Type: Bug
         Environment: Ubuntu 14.04
            Reporter: Ariel Weisberg
            Assignee: Ariel Weisberg


Starts as part of merge commit 25be46497a8df46f05ffa102bc645bfd684ea48a

Stress will say that a key wasn't validated because it isn't returned even though it's loaded. The key will eventually appear and can be queried using cqlsh.

Reproduce with
#!/bin/sh
rm /tmp/fark
ROWCOUNT=10000000
SCHEMA='-col n=fixed(1) -schema compaction(strategy=LeveledCompactionStrategy) compression=LZ4Compressor'
./cassandra-stress write n=$ROWCOUNT -node xh61 -pop seq=1..$ROWCOUNT no-wrap -rate threads=25 $SCHEMA
./cassandra-stress mixed "ratio(read=2)" n=100000000 -node xh61 -pop "dist=extreme(1..$ROWCOUNT,0.6)" -rate threads=25 $SCHEMA
