Subject [jira] [Resolved] (HADOOP-14161) Failed to rename file in S3A during FileOutputFormat commitTask
Date Wed, 22 Nov 2017 17:41:01 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-14161?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steve Loughran resolved HADOOP-14161.
-------------------------------------
       Resolution: Won't Fix
    Fix Version/s: 3.1.0

I'm closing this as a WONTFIX because the classic FileOutputFormat committer isn't the right
way to work with data in S3. It should work with HADOOP-13345 and the consistent listings
there, but performance will still suffer. 

# Short term (Hadoop 2.9+): use S3Guard for the consistency you need
# Longer term: Hadoop 3.1+: use the S3A Committers for the performance you want

> I'm getting non deterministic rename errors while writing to S3 using spark and hadoop.
The proper permissions are set and this only happens occasionally. It can happen on a job
that is as simple as reading in json, repartitioning and then writing out. After this failure
occurs, the overall job hangs indefinitely.
