Ruben Q L updated CALCITE-3598:
-------------------------------
Description:
Problem unveiled by CALCITE-3535, and also separately by CALCITE-3576.
When CALCITE-3535 was committed, it made
MaterializationTest#testJoinMaterialization8 and
MaterializationTest#testJoinMaterialization9 change their execution plan from
hashJoin to nestedLoopJoin. This caused an exception
{code}
java.lang.ClassCastException: java.lang.String$CaseInsensitiveComparator cannot
be cast to java.lang.String
{code}
which seems unrelated to CALCITE-3535 (or CALCITE-3576), so the tests were
temporarily disabled.
The goal of this ticket is to investigate the root cause of this issue and
re-activate both tests.
