Subject Re: [Spark-Submit] Where to store data files while running job in cluster mode?
Date Fri, 29 Sep 2017 15:31:45 GMT
We use S3, there are caveats and issues with that but it can be made to
work.

If interested let me know and I'll show you our workarounds.  I wouldn't do
it naively though, there's lots of potential problems.  If you already have
HDFS use that, otherwise all things told it's probably less effort to use
S3.
