Error in executing Customised WordCount jar in AWS EMR

Question

Hi I am trying to execute customised WordCount jar on AWs EMR.

My word count jar is working properly because I tried adding it as a step without job arguments and it is running successfully. My problem is when I run it with job arguments. In my s3 I have 2 folders

Jar location -> s3n://word-count123/WordCount.jar
jar Arguments ->s3n://word-count123/input
                s3n://word-count123/output

input folder contains one txt file and output folder one txt file. Am I doing something wrong? I can't seem to figure it out. Thanks.

P.S I dont wanna execute it from CLI.

Answer 1

Just executed a existing WordCount jar.. Seems to be a problem with my JAR.
