Andrew Davidson reopened SPARK-12111:
-------------------------------------

Hi Sean

It must be possible for customers to upgrade installations. Given Spark is written in java it is probably a matter of replacing jar files and maybe making a few changes to config files.

Who ever is responsible for build/release of spark can probably write down the instructions. Its not reasonable to say destroy your old cluster and re-install it. In my experience spark does not work out of the box. You have to do a lot of work to configure it properly. I have a lot of data on HDFS I can not simply move it

sincerely yours

Andy
