Key: CASSANDRA-9683
URL: https://issues.apache.org/jira/browse/CASSANDRA-9683
Project: Cassandra
Issue Type: Bug

JDK: Oracle JDK 7

Priority: Critical
Attachments: os_load.png, pending_compactions.png, read_latency.png,

After upgrading our cassandra staging cluster version from 2.1.6 to 2.1.7, the
average load grows from 0.1-0.3 to 1.8.
Latencies did increase as well.
We see an increase of pending compactions, probably due to CASSANDRA-9592.
This cluster has almost no workload (staging environment)
