Piotr Nowojski commented on FLINK-10211:
----------------------------------------
[~xccui] it looks so. I have discovered those bugs after looking at the code
(not from faulty queries), so I'm not 100% sure if the symptoms of those two
bugs are as described in https://issues.apache.org/jira/browse/FLINK-8897 .
This https://issues.apache.org/jira/browse/FLINK-10211 join bug probably can
cause it, however the other issue
(https://issues.apache.org/jira/browse/FLINK-10210) with LogicalCorrelate is an
not covered in https://issues.apache.org/jira/browse/FLINK-8897
> Time indicators are not always materialised for LogicalJoin
