apply(taskContext: TaskContext, writeConf: WriteConf): OutputMetricsUpdater
Creates the appropriate instance of
OutputMetricsUpdater
.Creates the appropriate instance of
OutputMetricsUpdater
.If WriteConf.taskWriteMetricsEnabled is
true
, the created instance will be updating task metrics so that Spark will report them in the UI. Remember that this is supported for Spark 1.2+.If CassandraConnectorSource is registered in Spark metrics system, the created instance will be updating the included Codahale metrics. In order to register

you need to add it to the metrics configuration file.- taskContext
