What changes were proposed in this pull request?
This patch proposes to check
ignoreNullability
parameter recursively inequalsStructurally
method. This backports #29698 to branch-3.0.Why are the changes needed?
equalsStructurally
is used to check type equality. We can optionally ask to ignore nullability check. But the parameterignoreNullability
is not passed recursively down to nested types. So it produces weird error like:when running the query
select aggregate(split('abcdefgh',''), array(array('')), (acc, x) -> array(array( x ) ) )
.Does this PR introduce any user-facing change?
Yes, fixed a bug when running user query.
How was this patch tested?
Unit tests.
