Pradeep Agrawal commented on RANGER-3687:
-----------------------------------------
[~kirbyzhou] /[~bpatel] :
1) At my end character set is utf8 (An alias for {{utf8mb3) and not the
utf8mb4. collation set is }}utf8_general_ci
2) Also, I will not suggest anyone to switch to utf8mb3 if they are already
using utf8mb4 in existing env. User need to do that as per their requirement
or if there is issue in ranger at the runtime(not during install) and switching
to utf8mb4 is the only option.
3) We are not explicitly assigning character set or collation in DB schema and
will never do that unless there is any valid reason for it. currently ranger db
schema script is independent of user's env. and by default it will follow
character set or collation as per their mysql engine.
