Tables to include (comma-separated list of table names)If not specified, includes all tables. A graceful transfer minimizes delays in tablet operations, but will fail if the tablet cannot arrange a successor. The configured value must match the Hive hive.metastore.uris configuration. You can use Impala Update command to update an arbitrary number of rows in a Kudu table. Use the 'checksum' flag to check that tablet data is consistent (also see the 'tables' and 'tablets' flags). In any case, we'd need a lot more logs from nod7.exp to understand what's going on. Usage: Drop orphan Hive Metastore tables which refer to non-existent Kudu tables.
