class CassandraConnectorSource extends Source

This class is a Source implementation for Cassandra Connector related Codahale metrics. It is automatically instantiated and registered by Spark metrics system if this source is specified in metrics configuration file.

Spark instantiates this class when SparkEnv is started. There can be only a single instance of SparkEnv so there can be at most a single active instance of CassandraConnectorSource. The active instance is assigned to CassandraConnectorSource._instance so that it can be retrieved from anywhere by CassandraConnectorSource.instance method. We need this because we have to access the meters from the task execution.
