@viirya has updated the description, hope it is clear now |
|
Thanks. As #32773 was also merged to 3.1, is this also an issue on branch-3.1 too? @ulysses-you |
|
I think land this to branch-3.2 is enough, since the backport of branch-3.1 is revered. |
|
Okay, thanks! Merging to master. |
|
Oh, there is a conflict. @ulysses-you Can you submit a backport PR to branch-3.2? Thanks. |

…ray inside a nested struct This is a backport of #35170 for branch-3.2. ### What changes were proposed in this pull request? Skip alias the `ExtractValue` whose children contains `NamedLambdaVariable`. ### Why are the changes needed? Since #32773, the `NamedLambdaVariable` can produce the references, however it cause the rule `NestedColumnAliasing` alias the `ExtractValue` which contains `NamedLambdaVariable`. It fails since we can not match a `NamedLambdaVariable` to an actual attribute. Talk more: During `NamedLambdaVariable#replaceWithAliases`, it uses the references of nestedField to match the output attributes of grandchildren. However `NamedLambdaVariable` is created at analyzer as a virtual attribute, and it is not resolved from the output of children. So we can not get any attribute when use the references of `NamedLambdaVariable` to match the grandchildren's output. ### Does this PR introduce _any_ user-facing change? yes, bug fix ### How was this patch tested? Add new test Closes #35175 from ulysses-you/SPARK-37855-branch-3.2. Authored-by: ulysses-you <ulyssesyou18@gmail.com> Signed-off-by: Liang-Chi Hsieh <viirya@gmail.com>
