I believe you need to take two jumps. I believe it is 15-> 18 -> 20.
I'd strongly suggest trying a practice file system first. Did we have
owners and perms in 15? If not, you'll need to set owners and perms.

Hi,
We 've been using hadoop 15.5 in our production environment where we
have about 10 TB of data stored on the dfs.
The files were generated as mapreduce output. We want to move our
env. to Amazon Elastic Map Reduce (EMR) which throws the following
questions to us:
1. EMR supports only hadoop 19.0 and above. Is it possible to use
the current data that were generated with hadoop 15.5 from hadoop
19.0?
2. Or how can we make it possible to use or update to hadoop 19.0
from hadoop 15.5? What are the issues expected while doing so?
