> Job hangs if S3 access it denied during checkpoints
> ---------------------------------------------------
>
> Key: FLINK-9450
> URL: https://issues.apache.org/jira/browse/FLINK-9450
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.4.2
> Reporter: Elias Levy
> Priority: Not a Priority
> Labels: auto-deprioritized-major, auto-deprioritized-minor
>
> We have a streaming job that consumes from and writes to Kafka. The job is
> configured to checkpoint to S3. If we deny access to S3 by using iptables on
> the TM host to deny all outgoing connections to ports 80 and 443, whether
> using DROP or REJECT, and whether using REJECT with -reject-with tcp-reset or
> -r reject-with imp-port-unreachable, the job soon stops publishing to Kafka.
> This happens whether or not the Kafka sources have
> {{setCommitOffsetsOnCheckpoints}} set to true or false.
> The system is configured to use Presto for the S3 file system. The job has a
> small amount of state, so it is configured to use {{FsStateBackend}} with
> asynchronous snapshots.
> If the ip tables rules are removed, the job continues the function.
> I would expect the job to either fail or continue running if a checkpoint
> fails.
