[jira] [Reopened] (CALCITE-1691) java.lang.ClassCastException:
org.apache.flink.table.codegen.ExpressionReducer cannot be cast to
org.apache.calcite.rex.RexExecutorImpl
[ https://issues.apache.org/jira/browse/CALCITE-1691?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Julian Hyde reopened CALCITE-1691:
----------------------------------
Re-opening. I believe this is valid. You are not obliged to provide an executor, and if you do, it does not need to extend RexExecutorImpl. The method should fail safe (return true) in that case.
