Spark Scala list folders in directory

Question

I want to list all folders within a hdfs directory using Scala/Spark. In Hadoop I can do this by using the command: hadoop fs -ls hdfs://sandbox.hortonworks.com/demo/<

Answer 1

val spark = SparkSession.builder().appName("Demo").getOrCreate()
val path = new Path("enter your directory path")
val fs:FileSystem = projects.getFileSystem(spark.sparkContext.hadoopConfiguration)
val it = fs.listLocatedStatus(path)

This will create an iterator it over org.apache.hadoop.fs.LocatedFileStatus that is your subdirectory
