IMPALA-14072: Fix NPE in Catalogd during rename.
test_rename_drop fail with NPE after IMPALA-14042. This is because
CatalogServiceCatalog.renameTable() return null for not finding the
database of oldTableName. This patch change renameTable() to return
Pair.create(null, null) for that scenario.
Refactor test_rename_drop slightly to ensure that invalidating the
renamed table and dropping it are successful.
Testing:
- Add checkNotNull precondition in
CatalogOpExecutor.alterTableOrViewRename()
- Increase catalogd_table_rename_delay delay to 6s to ensure that DROP
query happen in Catalogd before renameTable() called. Manually
observed that No NPE is shown anymore.
