Hi,

Currently I am looking into configuring in-transit data encryption either using Flink SSL Setup or directly using EMR.

Few Doubts:
   1. Will the existing functionality provided by Amazon to configure in-transit data encrytion work for Flink as well. This is explained here:
http://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-encryption-enable-security-configuration.html
http://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-data-encryption-options.html#emr-encryption-intransit

   2. Using Flink SSL Setup: as we know only the IP address of master node on EMR , should we pass only its ip address in the SAN list as given here ? (I think it should work as the yarn-cli command will distribute the truststore and keystore to each TM )
