[jira] [Created] (IMPALA-11447) Fetching arrays/structs crashes Impala if impala.resultset.cache.size is set

Csaba Ringhofer created IMPALA-11447:
----------------------------------------

             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
