---------------------------------------

             Summary: Rocksdb checkpointing failing with fs.default-scheme: hdfs:// config
                 Key: FLINK-8867
                 URL: https://issues.apache.org/jira/browse/FLINK-8867
             Project: Flink
          Issue Type: Bug
          Components: Configuration, State Backends, Checkpointing, YARN
    Affects Versions: 1.4.1, 1.4.2
            Reporter: Shashank Agarwal
             Fix For: 1.5.0, 1.4.3


In our setup, when we put an entry in our Flink_conf file for default schema.

{code}
fs.default-scheme: hdfs://mydomain.com:8020/flink
{code}

Than application with rocksdb state backend fails with the following exception. When we remove this config it works fine. It's working fine with other state backends.
