I'd be curious to see how others have done this, but our setup restricts
network access to machines in the YARN cluster to a jump box. Access to
Flink job manager is limited to whoever can ssh to that box, and that is
controlled with an Ansible playbook. Additionally, we have a list of users

Hey Flink Community,
I'm combing through docs right now, and I don't see that a savepoint
location is returned or surfaced anywhere. When I do this in the CLI, I get
a nice message that tells me where in S3 it put my savepoint (unique
savepoint ID included). I'm looking for that same result to be

Senthil,
One of the key steps in debugging this for me was enabling debug level logs
on my cluster, and then looking at the logs in the resource manager. The
failure you are after happens before the exceptions you have reported here.

Hello Flink Community,
I'm working on a HA setup of Flink 1.8.1 on AWS EMR and have some questions
about how Flink interacts with Zookeeper when one of the servers in the
quorum specified in flink-conf.yaml goes down and is replaced by a machine
with a new IP address.
Currently, I configure
Hello Flink Community,
I'm hoping to verify some understanding:
If I have a function with managed state, I'm wondering if a checkpoint will
ever be taken while a function is mutating state. I'll try to illustrate
the situation I'm hoping to be safe from:

Hello Flink Community,
I have a question about using MapState with lists as values. Here is a
description of the use case:
I have an operator over a keyed stream where for each record that comes, it
needs to look into some state to determine if a value has arrived or not.
If the value has not
Hey Flink Community,
I'm working on a Flink application where we are implementing operators that
extend the RichFlatMap and RichCoFlatMap interfaces. As a result, we are
working directly with Flink's state API (ValueState, ListState, MapState).
Something that appears to be extremely valuable is
