Monitoring folder in flink

[Sugandha Amatya]

I have folder where new files arrive at schedule. Why is my flink readfile
not reading new files. I have used but *PROCESS_ONCE* and
*PROCESS_CONTINUOUSLY*. When I use *PROCESS_CONTINUOUSLY* it reads the same
file but the execution does not terminate whereas for PROCESS_ONCE it
terminates in IDE.

    String path = "C:\\test";

StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();

    TextInputFormat format = new TextInputFormat(new
org.apache.flink.core.fs.Path(path));

    DataStream<String> inputStream = env.readFile(format, path,
FileProcessingMode.PROCESS_ONCE, 100);
