Hi,
I actually have no experience running a Flink job on K8s against a
kerberized HDFS so please take what I'll say with a grain of salt.
The only thing you should need to do is to configure the path of your
keytab and possibly some other Kerberos settings. For that check out [1]

1. Yes, StreamingExecutionEnvironment.readFile can be used for files on HDFS
2. I think this is a valid concern. Besides that, there are plans to
deprecate DataSet API [1]
4. Yes, the approach looks good
I'm pulling in Aljoscha for your 3rd question (and probably some
clarifications on others
