             Summary: Query failure due to large buffer allocation provides insufficient context
                 Key: IMPALA-11860
                 URL: https://issues.apache.org/jira/browse/IMPALA-11860
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 4.2.0
            Reporter: Michael Smith


When a query fails because SerializeToBuffer returns a "not OK" status in https://github.com/apache/impala/blob/4.2.0/be/src/runtime/query-state.cc#L646-L655, profile_len is always 0.

Usually if SerializeToBuffer returns "not OK" it's because it failed to allocate more buffer space, and often has already allocated some buffer. It would help to know how much buffer is allocated, so SerializeToBuffer should update profile_len before returning an error.
