-----------------------------------------
Any idea as to why things have changed?
> Listing s3a bucket without credentials gives Interrupted error
> --------------------------------------------------------------
>
> Key: HADOOP-14832
> URL: https://issues.apache.org/jira/browse/HADOOP-14832
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.0.0-beta1
> Reporter: John Zhuge
> Priority: Minor
>
> In trunk pseudo distributed mode, without setting s3a credentials, listing an
> s3a bucket only gives "Interrupted" error :
> {noformat}
> $ hadoop fs -ls s3a://bucket/
> ls: Interrupted
> {noformat}
> In comparison, branch-2 gives a much better error message:
> {noformat}
> (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
> {noformat}
