> Key: FLINK-10445
> URL: https://issues.apache.org/jira/browse/FLINK-10445
> Project: Flink
> Issue Type: Bug
> Components: Command Line Client, Runtime / REST
> Affects Versions: 1.5.4
> Reporter: Nico Kruber
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> I created a keystore with
> {code}
> keytool -genkeypair -alias flink.internal -keystore internal.keystore -dname
> "CN=flink.internal" -storepass internal_store_password -keypass
> internal_key_password -keyalg RSA -keysize 4096
> {code}
> and adapted {{flink-conf.yaml}} to point to this with the following
> configuration:
> {code}
> security.ssl.enabled: true
> web.ssl.enabled: false
> security.ssl.keystore: /path/to/internal.keystore
> security.ssl.keystore-password: internal_store_password
> security.ssl.key-password: internal_key_password
> security.ssl.truststore: /path/to/internal.keystore
> security.ssl.truststore-password: internal_store_password
> {code}
> Now I know that this setup is supposed to work with Flink 1.6+ but probably
> wrong for 1.5. However, I was able to start up a Flink cluster and tried to
> submit a job via
> {code}
> ./bin/flink run -p 1 ./examples/streaming/WordCount.jar --input
> /home/nico/Projects/flink/LICENSE
> {code}
> and nothing happened. The CLI was stuck at
> {code}
> Starting execution of program
> Printing result to stdout. Use --output to specify output path.
> {code}
> and the job did not show up in the Web UI. I can also not find anything
> related to the job submission in the JM log.
> Debugging into {{CliFrontend}}, it eventually enters
> {{RestClient#submitRequest}} but doesn't seem to get a response.
> {{RestClient.MultipartRequest#writeTo}} does add a listener on the future and
> debugging in there, the {{ignored}} object handed to the lambda is a
> {{DefaultChannelPromise@1a884b08(failure(java.nio.channels.ClosedChannelException)}}
> which looks like we should react on. However, that alone is not really
> enough information on the cause of the error and requires further
> investigation.
