TEOTEO520 opened a new pull request, #7789:
URL: https://github.com/apache/gravitino/pull/7789
### What changes were proposed in this pull request?
1. Added a merge function when collecting columns from catalog table
2. Added a merge function when collecting columns from table entity
### Why are the changes needed?
When loading tables from external catalogs (e.g., Hive), duplicate columns
can cause IllegalStateException: Duplicate key crashes. This commonly occurs
when:
- HiveTableConverter.getColumns() includes a partition field (e.g.,
log_date) from table.getSd().getCols()
- The same field also exists in table.getPartitionKeys()
- This results in duplicate columns in the final table schema
Fix: [#(issue)](https://github.com/apache/gravitino/issues/7788)
