URL: https://github.com/apache/hadoop/pull/8085#issuecomment-3745309207

   Looks like the javadoc warnings are for code that wasn't part of this PR(or 
a Logger variable). The spotbugs warnings about CT_CONSTRUCTOR_THROW are for 
code that is the same as the TaskAttempt codepath, so I'd assume I can ignore 
them.
   
   The Jenkins console output mentions the pipeline script terminating with 
exit code 5, but I can't find what that corresponds to. The steps called from 
the Jenkinsfile seem to execute fine.
   
   @steveloughran Let me know if I'm missing anything, otherwise this should be 
ready for a final review.

> The MagicS3GuardCommitter assumes that the JobID of the task is the same as 
> that of the job's application master when writing/reading the .pendingset 
> file. This assumption is not valid when running with Tez, which creates 
> slightly different JobIDs for tasks and the application master.
>  
> While the MagicS3GuardCommitter is intended only for MRv2, it mostly works 
> fine with an MRv1 wrapper with Hive/Pig (with some minor changes to Hive) run 
> in MR mode. This issue only crops up when running queries with the Tez 
> execution engine. I can upload a patch to Hive 3.1 to reproduce this error on 
> EMR if needed.
>  
> Fixing this will probably require work from both Tez and Hadoop, wanted to 
> start a discussion here so we can figure out how exactly we go about this.
