I just want to use HDFS.open in my Pyspark shell but get the following Error: Someone got an idea ? In Python it works I can use HDFS.Open function - In Pyspark I can not access the Namenode? I do not get why it works in Python but not in Pyspark? Python 2.7 (Anaconda 4) Spark 1.6.0 Hadoop 2.4 (Installed with Ambari) I also asked on Stackoverflow: Stackoverflow-Python-Pydoop-Hdfs 16/06/20 16:11:40 WARN util.NativeCodeLoader: Unable to load native-hadoop
