[jira] [Commented] (CALCITE-3488) Interpreter does not implement LogicalCorelate.

    [ https://issues.apache.org/jira/browse/CALCITE-3488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16970716#comment-16970716 ] 

Jin Xing commented on CALCITE-3488:
-----------------------------------

Currently RelDecorrelator doesn't support a decorrelateRel(Collect), that's why decorrelate failed

-- operator Collect should not reference correlate variables.

> Interpreter does not implement LogicalCorelate.
