| Issue/JIRA | Description | Workaround, if any |
|---|---|---|
| ANLY-6855 | DecisionTree and AdaBoost functions sometimes generate no rows for model table. Several situations can cause DecisionTree and AdaBoost functions to generate no rows for model table. For example:
|
None. |
| ANLY-6958 | If an error message exceeds 256 characters, it is truncated to 256 characters. | None. |
| ANLY-7955 | Argument names from versions prior to AA7.00 are no longer supported. | None. If existing queries use argument names that have not been included in user documentation since AA 6.21, rewrite these queries using more recent argument names. |
| ANLY-8244 | For KNN function, automatic tuning of PartitionBlockSize might not be optimal. | Manually tune value of PartitionBlockSize. |
| ANLY-8929 | Classification functions do not support class names that differ only by case. For example, functions may treat classes named "DeKalb" and "Dekalb" as one class. | Distinguish class names by more than case. |
| MLE-750 | User-defined function whose first output column has unbounded VARCHAR type causes CREATE TABLE AS (CTAS) statement to fail. | Create table either without primary index or with primary index on different column. |
| MLE-1392 | Stored procedures in pm database, such as pm.install_afile, fail if first master node in analytic cluster is unavailable. | Administrator must log into each TPA node using ssh, then change the file /home/tdatuser/.ssh/config to point to another node in analytic cluster. |
| MLE-2077 MLE-2244 |
For "HELP FOREIGN FUNCTION" calls for nPath® and NTree, the following fields are empty:

As db_superuser, use act to provide these grants:beehive> grant execute on function nc_system.ntree to public; beehive> grant execute on function nc_system.npath to public; |
| MLE-2220 | PERM space size of Query Level Monitoring (QLM) database is created with 10 Mb for each AMP. PERM space is full if QLM queries fail with this error: [Error 2644]: No more room in database td_mle_db. |
For information on increasing PERM space or deleting database rows, see KCS020410:
|
| MLE-2240 | CPUIOWaitCentiseconds collects stats by node, not by pod. CPUIOWaitCentiseconds node is displayed for each pod on which it is deployed. | None. |
| MLE-2363 | Some data points for query-level utilization stats are missing from collected data. | This happens too rarely to have material impact on collected statistics. |
| MLE-3031 | Some rows in MLE stats table are empty. | None. |
| MLE-3405 | ML Engine does not support QueryGrid link names that contain whitespace. | Do not use whitespace in names when creating links between ML Engine and other components. Doing so causes error in Failure Detection and Restart capability of ML Engine. |
| MLE-3491 | Remote connector stats handler thread continues to use old connector password. | Contact Teradata Customer Support for assistance. |
| MLE-3838 | Time zone may be different on ML Engine analytic nodes and NewSQL Engine. Analytic applications, such as ML Engine, use UTC time zone. NewSQL Engine may have been set to non-UTC time zone. Time zone must match between NewSQL Engine and the analytic applications; otherwise, data transferred between nodes is impacted. | Contact Teradata Customer Support for assistance. |
