Hi, wanglei

You could use the flink distributed cache to register some config files and then access them in your task.

1. Register a cached file

StreamExecutionEnvironment.registerCachedFile(inputFile.toString(), "test_data", false);

2. Access the file in your task

final Path testFile = getRuntimeContext().getDistributedCache().getFile("test_data").toPath();

When starting  a single node java application, I can add some config file to it.

How can i implenment it when submitting a flink job? The config file need to be read from taskMgr node and used to initialize some classess.
