Change subject: IMPALA-11509: Prevent query hanging when Iceberg metadata is missing. ...................................................................... IMPALA-11509: Prevent query hanging when Iceberg metadata is missing. Traditionally table metadata is loaded by the catalog and sent as thrift to the Impala daemons. With Iceberg tables, some metadata, for example the org.apache.iceberg.Table, is loaded in the Coordinator at the same time as the thrift description is being deserialized. If the loading of the org.apache.iceberg.Table fails, perhaps because of missing Iceberg metadata, then the loading of the table fails. This can cause an infinite loop as StmtMetadataLoader.loadTables() waits hopefully for the catalog to send a new version of the table. Prevent this situation by substituting a IncompleteTable if a TableLoadingException occurs. TESTING Add a new test originally developed for IMPALA-11330 which tests failures after deleting Iceberg metadata.
