Ma77Ball opened a new pull request, #58750: URL: https://github.com/apache/spark/pull/58750
### What changes were proposed in this pull request? Rename the legacy error condition `_LEGACY_ERROR_TEMP_1060` to the named subclass `UNSUPPORTED_FEATURE.NESTED_COLUMN` (SQLSTATE `0A000`). It is raised when a command such as `DESC TABLE COLUMN` or JDBC filter push down is given a nested column it cannot operate on. ### Why are the changes needed? The error-conditions README disallows new `_LEGACY_ERROR_TEMP_*` entries and asks existing ones to be resolved. This resolves one (part of SPARK-37935). ### Does this PR introduce _any_ user-facing change? Yes. The condition becomes `UNSUPPORTED_FEATURE.NESTED_COLUMN`, and the rendered message gains the standard `The feature is not supported:` prefix and quotes the column with backticks, e.g. ``The feature is not supported: DESC TABLE COLUMN does not support nested column `col.x`.`` ### How was this patch tested? Updated the existing `checkError` test in `DataSourceV2SQLSuite` and converted the message assertion in `DescribeTableSuiteBase` to `checkError`. `SparkThrowableSuite` passes. ### Was this patch authored or co-authored using generative AI tooling?
