[jira] [Created] (HADOOP-14283) S3A may hang due to bug in AWS SDK 1.11.86

Aaron Fabbri created HADOOP-14283:
-------------------------------------

             Summary: S3A may hang due to bug in AWS SDK 1.11.86
                 Key: HADOOP-14283
                 URL: https://issues.apache.org/jira/browse/HADOOP-14283
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/s3
    Affects Versions: 3.0.0-alpha2
            Reporter: Aaron Fabbri
            Assignee: Aaron Fabbri
            Priority: Critical


We hit a hang bug when testing S3A with parallel renames.  

I narrowed this down to the newer AWS Java SDK.  It only happens under load, and appears to be a failure to wake up a waiting thread on timeout/error.

I've created a github issue here:
https://github.com/aws/aws-sdk-java/issues/1102

I can post a Hadoop scale test which reliably reproduces this after some cleanup.  I have posted an SDK-only test here which reproduces the issue without Hadoop:

I have a support ticket open and am working with Amazon on this bug so I'll take this issue.
