Did you build Spark against your cluster's Hadoop version? Do you mind
posting the build command that you used?
> Py4JJavaError: An error occurred while calling
z:org.apache.spark.api.python.PythonRDD.hadoopFile.
: java.lang.ClassCastException:
org.apache.avro.mapreduce.AvroKeyInputFormat cannot be cast to
org.apache.hadoop.mapred.InputFormat
You need to use `newAPIHadoopFile`, not `hadoopFile`, since
`mapreduce.InputFormat`s can only be used with that API.
