----------------------------------------
Summary: Fetching arrays/structs crashes Impala if
impala.resultset.cache.size is set
Key: IMPALA-11447
URL: https://issues.apache.org/jira/browse/IMPALA-11447
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 4.1.0
Reporter: Csaba Ringhofer
HS2ColumnarResultSet::AddRows(const QueryResultSet* other ... ) is not prepared
for handling complex types:
https://github.com/apache/impala/blob/1d16367afb1e520bae5992c1e6c92b4fb41d2655/be/src/service/query-result-set.cc#L412
A debug build will hit the DCHECK, while a release build will crash a bit
later. This didn't come up during testing as impala-shell doens't set
impala.resultset.cache.size
