> EnumerableTableScan: wrong JavaRowFormat for elementType String
> ---------------------------------------------------------------
>
> Key: CALCITE-3598
> URL: https://issues.apache.org/jira/browse/CALCITE-3598
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.21.0
> Reporter: Ruben Q L
> Assignee: Ruben Q L
> Priority: Minor
> Labels: pull-request-available
> Fix For: 1.22.0
>
> Attachments: codeHashJoin.txt, codeNestedLoopJoin.txt
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> 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.
