--------------------------------------
Summary: Tuple caching correctness verification can't handle
STRUCT types
Key: IMPALA-13892
URL: https://issues.apache.org/jira/browse/IMPALA-13892
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 5.0.0
Reporter: Joe McDonnell
Tuple caching correctness verification relies on debug-util's PrintRow().
PrintRow() can write some collection types, but it does not currently write
structs. With a fix for IMPALA-13886, running the following SQL twice crashes
Impala:
{noformat}
select nested_struct from functional_parquet.complextypestbl;{noformat}
It hits this DCHECK:
{noformat}

c440c38c551d001d:ee76eec100000001] Check failed: false Unknown type:
