单个Spark Streaming使用者可以侦听多个HDFS目录

Question

我知道Spark Streaming消费者可以收听HDFS目录。

val conf = new SparkConf().set("spark.executor.extraClassPath", "/home/hadoop/spark/conf:/home/hadoop/conf:/home/hadoop/spark/classpath/emr/*:/home/hadoop/spark/classpath/emrfs/*:/home/hadoop/share/hadoop/common/lib/*:/home/hadoop/share/hadoop/common/lib/hadoop-lzo.jar")

val ssc = new StreamingContext(conf, Seconds(5))
ssc.checkpoint("/name/spark-streaming/checkpointing")

val lines = ssc.textFileStream("hdfs:///name/spark-streaming/data/")

但是，我想知道同一个Streaming消费者是否可以收听多个HDFS目录。
