Issues with Flink1.5 SQL-Client

[Ashwin Sinha]

Hi folks,

We are trying to setup flink sql client. It is still in development phase, but flink-1.5 contains beta version of this feature.

Our environment:

Kafka-
Topic: test_flink_state_check

Kafka Key: null
Kafka Value example: {"state": 299, "number": 299} 

Flink-
Jobmanager: http://localhost:8080/
conf/sql-client-defaults.yaml: https://pastebin.com/zGb3qs7E

Then we start sql-client shell by 

./bin/sql-client.sh embedded

When we run

select * from [tablename]

the result shell hangs and after sometime it exits without printing any data and give following error on screen: https://pastebin.com/wuitQx1a

Complete stacktrace in flink logs: https://pastebin.com/mgk06xeG

Please assist us in resolving this!

Hi Ashwin,

which Flink version is your (local cluster)? Are you executing Flink in the default (new deployment) or legacy mode? The SQL client supports only the new "FLIP-6" deployment model. I'm not sure about your error message but it might be related to that.

Regards,
Timo

Hi Timo, 

Our flink version is 1.5.0

We followed this documentation and started flink cluster same way. Also we are getting more logs https://pastebin.com/fGTW9s2b

Can you provide us with the JobManager logs?

Based on the exception i concur with Timo, it looks like the server is either running 1.4 or below, or was started in the legacy mode.

Hi Ashwin,

I encountered this problem before. You should make sure that the version for your Flink cluster and the version you run the SQL-Client are exactly the same.

Best,

Xingcan

Hi Chesnay, 

We got the issue. Thanks for pointing out the issue. By mistake it was running the 1.3.2 jobmanager version, and now moved to 1.5.0 and working smooth. Will be careful from next time.

Thanks for all the support and help!
