Description
I've run a simple program on a local cluster. It always fails with code Version: 1.3-SNAPSHOTCommit: e24a866.
Zhuoluos-MacBook-Pro:build-target zhuoluo.yzl$ bin/flink run -c com.alibaba.blink.TableApp ~/gitlab/tableapp/target/tableapp-1.0-SNAPSHOT.jar
Cluster configuration: Standalone cluster with JobManager at localhost/127.0.0.1:6123
Using address localhost:6123 to connect to JobManager.
JobManager web interface address http://localhost:8081
Starting execution of program------------------------------------------------------------
The program finished with the following exception:java.lang.NullPointerException

I don't think there should be a NullPointerException here, even if you forgot the "execute()" call.
The reproducing code looks like following:
public static void main(String[] args) throws Exception { ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment(); DataSource<String> customer = env.readTextFile("/Users/zhuoluo.yzl/customer.tbl"); customer.filter(new FilterFunction<String>() { public boolean filter(String value) throws Exception { return true; } }) .writeAsText("/Users/zhuoluo.yzl/customer.txt"); // env.execute(); }
We can use start-cluster.sh on a local computer to reproduce the problem.
