Question

flink version: 1.15.3 and jdk versioin: 1.8
conf/flink-conf.yaml file here:
jobmanager.rpc.address: test1
jobmanager.rpc.port: 6123
jobmanager.bind-host: test1
taskmanager.bind-host: test1
taskmanager.host: test1
taskmanager.numberOfTaskSlots: 2
parallelism.default: 2
start a local cluster:
./bin/start-cluster.sh
Starting the SQL Client CLI by calling:
./bin/sql-client.sh embedded
then enter the simple query below and press Enter to execute it.
SET 'sql-client.execution.result-mode' = 'tableau';
SET 'execution.runtime-mode' = 'batch';
SELECT
name,
COUNT(*) AS cnt
FROM
(VALUES ('Bob'), ('Alice'), ('Greg'), ('Bob')) AS NameTable(name)
GROUP BY name;
I got error:
