Using YARN w/o HDFS

["Alaa Zubaidi (PDF)" <al...@pdf.com>]

Hi,

Can we run Spark on YARN with out installing HDFS?
If yes, where would HADOOP_CONF_DIR point to?

Regards,

you'll need a filesystem with

* consistency
* accessibility everywhere
* supports a binding through one of the hadoop fs connectors

NFS-style distributed filesystems work with file:// ; things like glusterfs need their own connectors.

you can use azure's wasb:// as a drop in replacement for HDFS in Azure.I think google cloud storage is similar, but haven't played with it. Ask google.

You cannot do the same for S3 except on EMR and Amazon's premium emrfs:// offering, which adds the consistency layer.
