----------------------------------------------------
Summary: Switch Stress from using math3.pair because it is
unserializable
Key: CASSANDRA-7559
URL: https://issues.apache.org/jira/browse/CASSANDRA-7559
Project: Cassandra
Issue Type: Bug
Components: Tools
Reporter: Russell Alexander Spitzer
Stress uses org.apache.commons.math3.util.Pair to hold information in settings
because eventually it is used in commons.math3.distributions. This makes the
settings unserializable so we can't run with StressDemon.

Control-C caught. Canceling running action and shutting down...
{code}
To fix this we can pass around serializable pairs and convert to commons.math3
pairs before we actually pass the objects to the distribution code.
