Description

In trunk pseudo distributed mode, without setting s3a credentials, listing an s3a bucket only gives "Interrupted" error :

$ hadoop fs -ls s3a://bucket/
ls: Interrupted

In comparison, branch-2 gives a much better error message:

(branch-2)$ hadoop_env hadoop fs -ls s3a://bucket/
ls: doesBucketExist on hdfs-cce: com.amazonaws.AmazonClientException: No AWS Credentials provided by BasicAWSCredentialsProvider EnvironmentVariableCredentialsProvider InstanceProfileCredentialsProvider : com.amazonaws.SdkClientException: Unable to load credentials from service endpoint
