> Components: Ozone Client
> Reporter: Nandakumar
> Priority: Major
> Labels: Triaged

> We are throwing {{IllegalArgumentException}} in OzoneClient when the pipeline
> returned by SCM doesn't have any datanode information. Instead of throwing
> {{IllegalArgumentException}}, we can throw custom user friendly exception
> which is easy to understand.
> Existing exception trace:
> {noformat}
