> Project: Falcon
> Issue Type: Sub-task
> Components: general

>
> A read/write endpoint is currently validated by creating a filesystem with
> the endpoint url.
> {code}
> HadoopClientFactory.get().createProxiedFileSystem(conf);
> {code}
> This is not sufficient validation for read/write endpoint. It wont catch any
> typos in the url used for the endpoint. The validation of cluster will then
> fail in validateLocations(...) method, and will throw an exception that can
> confuse the user. Better validation would be to check if "/" exists in HDFS.
