-------------------------------------------------------------
[~liliwei] We have move FLINK-24024 to 1.15 because Session window TVF syntax
need to upgraded to SQL standard. Please see more discussion in FLINK-24024 .
So we don't need to verify this function in Flink 1.14 version. I'm very sorry
if this cause problem for you. [~liliwei] cc [~xtsong]
