>                 Key: HADOOP-14237
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14237
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs/s3
>    Affects Versions: 2.8.0, 3.0.0-alpha1, 3.0.0-alpha2, 2.8.1
>         Environment: EC2, AWS
>            Reporter: Kazuyuki Tanimura
>            Assignee: Kazuyuki Tanimura
> When I run a large Hadoop cluster on EC2 instances with IAM Role, it fails getting the
instance profile credentials, eventually all jobs on the cluster fail. Since a number of S3A
clients (all mappers and reducers) try to get the credentials, the AWS credential endpoint
starts responding 5xx and 4xx error codes.
> SharedInstanceProfileCredentialsProvider.java is sort of trying to solve it, but it still
does not share the credentials with other EC2 nodes / JVM processes.
> This issue prevents users from creating Hadoop clusters on EC2
