[jira] [Created] (SPARK-29103) CheckAnalysis for data source V2 ALTER TABLE ignores case sensitivity

Jose Torres created SPARK-29103:
-----------------------------------

             Summary: CheckAnalysis for data source V2 ALTER TABLE ignores case sensitivity
                 Key: SPARK-29103
                 URL: https://issues.apache.org/jira/browse/SPARK-29103
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Jose Torres


For each column referenced, we run

```val field = table.schema.findNestedField(fieldName, includeCollections = true)```

and fail analysis if the field isn't there. This check is always case-sensitive on column names, even if the underlying catalog is case insensitive, so it will sometimes throw on ALTER operations which the catalog supports.
