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. was: Problem unveiled by CALCITE-3535, and also separately by CALCITE-3576.
