-------------------------------------
Summary: Fetcher: java.lang.IllegalArgumentException: Wrong FS: s3
Key: NUTCH-2494
URL: https://issues.apache.org/jira/browse/NUTCH-2494
Project: Nutch
Issue Type: Bug
Components: fetcher, parser
Affects Versions: 1.14
Environment: * AWS EMR Cluster
* AWS S3
* Hadoop 2.2.7
Reporter: Ashraful Islam
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.
{code:bash}
bin/crawl -s s3://nutch-emr-cluster/test/crawl/urls s3://nutch-emr-cluster/test/crawl 1
{code}
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`
Full stacktrace
{code:java}
