The configuration does not specify the checkpoint directory 'state.checkpoints.dir' - apache-flink

Question

While submitting the flink job on the dataproc cluster getting the below error. Please find the code base and the error. I am using the flink 1.9.3 version.
The program finished with the following exception:

Code snippet I executed
public class ReadFromPubsub
{
public static void main(String args[]) throws Exception
{
System.out.println("Flink Pubsub Code Read 1");
StreamExecutionEnvironment streamExecEnv = StreamExecutionEnvironment.getExecutionEnvironment();
System.out.println("Flink Pubsub Code Read 2");
DeserializationSchema<String> deserializer = new SimpleStringSchema();
System.out.println("Flink Pubsub Code Read 3");
SourceFunction<String> pubsubSource = PubSubSource.newBuilder()
.withDeserializationSchema(deserializer)
.withProjectName("vz-it-np-gudv-dev-vzntdo-0")
.withSubscriptionName("subscription1")
.build();
System.out.println("Flink Pubsub Code Read 4");
streamExecEnv.addSource(pubsubSource).print();
streamExecEnv.enableCheckpointing(10);
System.out.println("Flink Pubsub Code Read 5");
streamExecEnv.execute();
}
}
I can see all the print statements during the execution of the code. After the last print statement I am getting the error.
All the exceptions to be resolved

Generally, you would supply the appropriate savepoint/checkpointing directory within your Flink configuration within flink-conf.yaml as detailed in the docs. If you aren't currently setting it, you can do so in the following ways:
Via flink-conf.yaml (Preferred)
state.checkpoints.dir: "file://example/checkpoints"
Programmatically (within the job):
Configuration configuration = new Configuration();
conf.setString("state.checkpoints.dir", "file://example/checkpoints");
StreamExecutionEnvironment streamExecEnv =
StreamExecutionEnvironment.getExecutionEnvironment(configuration);
Via the CLI:
flink run -Dstate.checkpoints.dir="/example/checkpoints" your-job.jar
Additionally, if you didn't actually want to perform checkpointing, you could likely remove the following configuration within your job:
streamExecEnv.enableCheckpointing(10);
