hadoop - Pyspark: get list of files/directories on HDFS path

As per title. I'm aware of textFile but, as the name suggests, it works only on text files. I would need to access files/directories inside a path on either HDFS or a local path. I'm using pyspark.

Using JVM gateway maybe is not so elegant, but in some cases the code below could be helpful:

URI           = sc._gateway.jvm.java.net.URI
Path          = sc._gateway.jvm.org.apache.hadoop.fs.Path
FileSystem    = sc._gateway.jvm.org.apache.hadoop.fs.FileSystem
Configuration = sc._gateway.jvm.org.apache.hadoop.conf.Configuration


fs = FileSystem.get(URI("hdfs://somehost:8020"), Configuration())

status = fs.listStatus(Path('/some_dir/yet_another_one_dir/'))

for fileStatus in status:
    print(fileStatus.getPath())
