@ygf11 Do you find the root cause why the panic happened? ``` It seems the partition of right child may execute one more time in NestedLoopJoin, if it has multiple output partitions. It is ok in most time, but when meets RepartitionExec it will panic. ``` From your example, the left side is partitioned and the right side is required single-partitioned. The output partition should be consistent with left side. The right single-partition will be executed one more time, is it not allowed to be called multiple times? Maybe it is the point why it caused panic @alamb -- This is an automated message from the Apache Git Service.
