i have a flink job that uses redis as a sink. i optionally do some wiping and metadata writing from the job submitting flink program before it actually executes/submits the job to the job manager. when i don't do this redis preparation, the redis sink works completely fine. that is, the redis commands work fine from the taskmanager tasks. however, if i enable the option redis preparation from within the flink job program, it fails to contact redis and hits a timeout exception.
previously, we were using 1.12.3, and this behavior worked fine. is the 1.14.4 flink docker image pretty restrictive when it comes to network access at the job submission client layer? thanks.
