I am using Apache Flink(v1.10.0) to stream compute my RabbitMQ data, but when I config the check point data to store NFS file system like this:
env.setStateBackend(new FsStateBackend("nfs://28736435.boston.nas.amazonaws.com:/data/k8s/data/flink/checkpoint"));
give me this error:

The manual says it support NFS file system to store check points. where I am doing wrong with NFS file system config in Apache Flink?
