Hadoop 2.6.2 upgrade and testing- can you please help me better test cases to test this upgrade on our environment.

[#1]

From admin prospective we do have some cases but from a developer prospective what are the best practices to check the upgrade in test env is good and what are the best test cases to conclude now our data is looking good in this enviornment when we deploy, we are good to go with the upgrade activity on PROD

For example,

1. we are deploying 5 tables with 1M data and testing it

2. Full loads and Incremental loads

any other test cases do you suggest?

From dev perspective you need to test you applications on newer version and recompile them with new dependencies as required.
