RiakError: 'Expected status [200, 201, 204, 300], received 503'

503 is caused by overload request shedding or timeouts (unless you have an HTTP proxy in front of Riak and it is limiting requests).

Closing in favor of the more generic error handling in #112.

[Basho-JIRA]

More general error handling in #112 to resolve this
