What failure mode is likely here?
As the uploads are signed, the network payload is not corruptible from the
moment its written into the HTTPS request, which places it earlier

I got no error messages from EMR. We write directly from dataframe to S3. There

I suspect we need to write to HDFS first, make sure we can read bac

I'd advocate 2.7 over 2.6, primarily due to Kerberos and JVM versions
2.6 is not even qualified for Java 7, let alone Java 8: you've got no
guarantees that things work on the min Java version Spark requires.
Kerberos is always the failure point here, as well as various libraries (jetty)
which
I wouldn't say we have a primary failure mode that we deal with. What we
concluded was that all the schemes we came up with to avoid corruption
couldn't cover all cases. For example, what about when memory holding a
value is corrupted just before it is handed off to the writer?
That's why we track
