Hi, I am reading files using textFileStream, performing some action onto it and then saving it to HDFS using saveAsTextFile. But whenever there is no file to read, Spark will write and empty RDD( [] ) to HDFS. So, how to handle the empty RDD.
I checked rdd.isEmpty() and rdd.count>0, but both of them does not works. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
