> Key: AMBARI-13020
> URL: https://issues.apache.org/jira/browse/AMBARI-13020
> Project: Ambari
> Issue Type: Bug
> Components: ambari-web
> Affects Versions: 2.0.0
> Reporter: Rick Kellogg
>
> The Storm transactional.zookeeper.servers property needs to be stored as a
> YAML array. This means that when extracting and storing this property, the
> web client must use the correct formatting.
> If the field is filled in with a single value, the resulting storm.yaml file
> created a String. This in turn causes a casting exception within the
> ZkState.newCurator method during parsing. It expects a List of String.
> Correct logic already exists to handle nimbus.seeds and
> storm.zookeeper.servers properties,
