In large parallelism. The request url to get watermark metric seems to too long  to get response.  The request url  is:

[http://0.0.0.0:8081/jobs/:jobid/vertices/:vertexid/metrics?get=0.currentInputWatermark,......,1199.currentInputWatermark]

The reason is org.apache.flink.shaded.netty4.io.netty.handler.codec.TooLongFrameException: An HTTP line is larger than 4096 bytes.

 

It need to paginate request and merge the result.
