Sandeep commented on SPARK-15849:
---------------------------------
Thanks Thomas for that comment. I have verified both the things with direct
committer :
1. The inconsistency issue no longer occurs
2. I see a 2x speedup too
Looking forward to the fix directly in Hadoop, so that the knob doesnt have to
be explicitly set

> Key: SPARK-15849
> URL: https://issues.apache.org/jira/browse/SPARK-15849
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.6.1
> Environment: AWS EC2 with spark on yarn and s3 storage
> Reporter: Sandeep
>
> When submitting spark jobs to yarn cluster, I occasionally see these error
> messages while doing saveAsTable. I have tried doing this with
> spark.speculation=false, and get the same error. These errors are similar to
> SPARK-2984, but my jobs are writing to S3(s3n) :
> Caused by: java.io.FileNotFoundException: File
> s3n://xxxxxxx/_temporary/0/task_201606080516_0004_m_000079 does not exist.
