> Add support for Tez to MagicS3GuardCommitter
> --------------------------------------------

> Key: HADOOP-19091
> URL: https://issues.apache.org/jira/browse/HADOOP-19091
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/s3
> Affects Versions: 3.3.6
> Environment: Pig 17/Hive 3.1.3 with Hadoop 3.3.3 on AWS EMR 6-12.0
> Reporter: Venkatasubrahmanian Narayanan
> Assignee: Venkatasubrahmanian Narayanan
> Priority: Major
> Labels: pull-request-available
> Attachments: 0001-AWS-Hive-Changes.patch,

> 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.
