--------------------------------------
Assignee: Michael Smith
> 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
> Assignee: Michael Smith
> Priority: Major
>
> 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.
