> While working on a prototype of integration between Oozie and the Kite SDK (see https://issues.cloudera.org/browse/CDK-385), I came to find that URIHandlerService.getAuthorityWithSchema(String uri) doesn't support URI schemes where there is a query string, but no path segment.
> I am currently prototyping Kite Dataset URIs and in my prototype, a Dataset URI for a dataset in a Hive/HCatalog DatasetRepository with managed Hive/HCatalog tables could look like this:
> repo:hive://localhost:9043?dataset-name=Person&partition-key=\[201405091300\]
> I am attempting to create an Oozie dataset around this Kite dataset and to make that happen I have implemented Oozie's URIHandler API for the Kite "repo" URI scheme. When I attempted to run my first coordinator, it failed.
> The coordinator has the following dataset definition:
> {code}
> <dataset name="Person" frequency="${coord:minutes(5)}" initial-instance="2014-04-24T00:00Z" timezone="UTC">
> <uri-template>repo:hive://localhost:9083?dataset-name=Person&partition-key=[${YEAR}${MONTH}${DAY}${HOUR}${MINUTE}]
> </uri-template>
> </dataset>
> {code}
> This dataset is used as an output of the coordinator.
> When the coordinator is submitted it fails with the following exception:
> {code}

> The problem is that URIHandlerService.getAuthorityWithScheme(String uri) doesn't consider the possibility that the URI might have a query string and no path segment. As a result, it ends up trying to create a URI from the entire URI template, which blows up due to $ in the template parameters.
