             Summary: Memory leak in C++ server metadata handler
                 Key: DRILL-5368
                 URL: https://issues.apache.org/jira/browse/DRILL-5368
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - C++
    Affects Versions: 1.10.0
            Reporter: Laurent Goujon
            Assignee: Laurent Goujon
            Priority: Minor


When receiving server metadata response, a protobuf ServerMetaResp object is 
dynamically allocated but never freed.

Since for this handler, there's no need to keep the instance attached to the 
handler (content is copied over by the MetaData class), a reference is enough 
and allocation can be done on the stack.
