The configuration does not specify the checkpoint directory 'state.checkpoints.dir'
问题
在 Dataproc 集群上提交 Flink 作业时出现以下错误。请找出代码基础和错误。我正在使用 Flink 1.9.3 版本。
程序以以下异常结束：
org.apache.flink.client.program.ProgramInvocationException: 无法检索执行结果。(JobID: f064ceaa5b318fdad9a77b2723b9ee64)

我执行的代码片段：
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();
}
}
我可以看到代码执行过程中的所有打印语句。在最后一个打印语句后，我遇到了错误。
需要解决所有的异常。

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

一般来说，在 Flink 配置文件 flink-conf.yaml 中提供适当的保存点（savepoint）/检查点（checkpoint）目录，具体细节可在文档中找到。如果您尚未进行设置，可以通过以下方式进行设置：
通过 flink-conf.yaml 文件（首选）
state.checkpoints.dir: "file://example/checkpoints"
通过编程方式（在作业内部）：
Configuration configuration = new Configuration();
conf.setString("state.checkpoints.dir", "file://example/checkpoints");
StreamExecutionEnvironment streamExecEnv =
StreamExecutionEnvironment.getExecutionEnvironment(configuration);
通过 CLI：
flink run -Dstate.checkpoints.dir="/example/checkpoints" your-job.jar
此外，如果您实际上并不希望执行检查点操作，您可以在作业中删除以下配置：
streamExecEnv.enableCheckpointing(10);
英文:
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);
