a directory in HDFS named /data/input. The Jar is named j.jar, and the driver class is named
DriverClass. She runs command:
hadoop jar j.jar DriverClass /data/input/data/output
The error message returned includes the line:
PrivilegedActionException as:training (auth:SIMPLE)
cause.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exits: file
