Carlo Curino commented on YARN-6853:
------------------------------------
[~giovanni.fumarola], thanks for the contribution. The patch looks fine, as it
is rather similar to the SQLServer one, we reviewed before. A couple of small
asks:
# In documentations, should we provide examples for both mysql and sql-server?
# The field {{params}} of table {{policies}} is set to be varbinary(512), I
think it would be best to be longer, as the payload might be large in some
cases (lots of subclusters, etc..).
# In documentations, call-out that the users are supposed to set their own
proper passwords in {{FederationStateStoreUser.sql}}, or use proper user/pass
setup. The script is comfy to include for testing, but we need to call out
prominently that proper user/pass setup is required.

> In YARN-3663 we added the SQL scripts for SQLServer. We want to add the MySql
> scripts to be able to run Federation with a MySQL servers which will be less
> performant but convenient.
