---------------------------------------
Summary: QueryNode does not respect null values for opState or
state
Key: HDDS-2349
URL: https://issues.apache.org/jira/browse/HDDS-2349
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Components: SCM
Affects Versions: 0.5.0
Reporter: Stephen O'Donnell
Assignee: Stephen O'Donnell
In HDDS-2197, the queryNode API call was changed to allow operational state
(in_service, decommissioning etc) to be passed along with the node health
state. This changed allowed for a null state to indicate a wildcard, so passing:
opState = null
healthState = HEALTHY
Allows one to find all the healthy nodes, irrespective of their opState.
However, for an enum protobuf field, if no value is specified, the first enum
in the set is returned as the default. This means that when a null is passed
for opState, only the IN_SERVICE nodes are returned. Similar for health state -
passing a null will return only HEALTHY nodes.
This PR will fix this issue so the null value acts as a wildcard as intended.
