      Description

      We are using nutch 1.14 in AWS EMR Cluster (Hadoop 2.2.7). trying to use S3 as main storage.

      We are using the below command.

      bin/crawl -s s3://nutch-emr-cluster/test/crawl/urls s3://nutch-emr-cluster/test/crawl 1
      

      Injector and Generator completed successfully without any error and data written perfectly into S3. But in the Fetcher and Parser steps we are getting IllegalArgumentException
