IMPALA-14233: Fix unexpected Kudu table drop attempt on external table creation
failure
The existing code incorrectly attempts to drop the corresponding
Kudu table when the creation of a Kudu external table in HMS fails due
to an erroneous negation in the if condition (fortunately, there are
additional checks with Preconditions in KuduCatalogOpExecutor.dropTable,
causing such attempts to always fail). Additionally, when creating a
Kudu synchronized table, if the table creation fails in HMS, it will
unexpectedly skip deleting the corresponding Kudu table, resulting in an
"already exists in Kudu" error when retrying the table creation.
Removed the incorrect negation in the if condition to align with the
intended behavior described in the comment.
Testing:
- Existing tests cover this change.
