MaxGekk opened a new pull request #30594: URL: https://github.com/apache/spark/pull/30594
### What changes were proposed in this pull request? In the PR, I propose to change the order of post-analysis checks for the `ALTER TABLE .. ADD/DROP PARTITION` command, and perform the general check (does the table support partition management at all) before specific checks. ### Why are the changes needed? The error message for the table which doesn't support partition management can mislead users: ```java PartitionSpecs are not resolved;; 'AlterTableAddPartition [UnresolvedPartitionSpec(Map(id -> 1),None)], false +- ResolvedTable org.apache.spark.sql.connector.InMemoryTableCatalog@2fd64b11, ns1.ns2.tbl, org.apache.spark.sql.connector.InMemoryTable@5d3ff859 ``` because it says nothing about the root cause of the issue. ### Does this PR introduce _any_ user-facing change? Yes. After the change, the error message will be: ``` Table ns1.ns2.tbl can not alter partitions ``` ### How was this patch tested? By running the affected test suite `AlterTablePartitionV2SQLSuite`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
