Subject [jira] [Commented] (HADOOP-14283) S3A may hang due to bug in AWS SDK 1.11.86
Date Fri, 14 Apr 2017 17:49:42 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14283?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15969327#comment-15969327
] 

Aaron Fabbri commented on HADOOP-14283:
---------------------------------------

This has been fixed in 1.11.119 ([github issue|https://github.com/aws/aws-sdk-java/issues/1102]),
so we just need to upgrade our SDK version to resolve this.

>             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:
> https://github.com/ajfabbri/awstest
> I have a support ticket open and am working with Amazon on this bug so I'll take this
issue.
