> Currently the WebHDFS client reuses the configuration of DFSClient to construct its RetryPolicy. This is problematic because:
> 1. It makes the WebHDFS client depends on the DFSClient.
> 2. The default values of the RetryPolicy of DFSClient might be ill fit for the WebHDFS client, which transfers all data using HTTP.
> This JIRA proposes to introduce new configuration keys for WebHDFS to resolve this problem.
