Cassandra Distributed DB pattern - IRE payload missing matching attributes - nodetool URISyntaxException: 'Malformed IPv6 address at index 7: rmi://[127.0.0.1]:7199' for upgraded JDK 8u331DescriptionPattern Cassandra Distributed DB fails with the following IRE error: Identification CI Errors: 2023-01-11 01:26:26: Identification CI Errors:Update failed with error: Commit was not attempted due to other errors.,In payload missing minimum set of input values for criterion (matching) attributes from identify rule for table [cmdb_ci_cassandra_instance]. Add these input values in payload item '{"className":"cmdb_ci_cassandra_instance","values":{... When troubleshooting further in the Pattern Log you encounter the following error on the "Get Cluster Name" step or any other step that uses the nodetool command. Get Cluster Name 2023-01-11 04:26:10: Executing SSH command: /opt/nosql/dse-6.0.15/bin/nodetool describecluster 2023-01-11 04:26:11: Command result: nodetool: Failed to connect to '127.0.0.1:7199' - URISyntaxException: 'Malformed IPv6 address at index 7: rmi://[127.0.0.1]:7199'. 2023-01-11 04:26:11: Command failed with status 12023-01-11 04:26:11: Execution time: 1344 ms Cause This issue is caused by Cassandra with the 8u33 JDK, specific versions of Cassandra/Nodetool component: The URL parser for JNDI providers which includes RMI (used by JMX) has been improved in Oracle Java 8u331 and brackets are only allowed around IPv6 addresses (JDK-8278972). Note:There are other problems giving the same IRE error. Please make sure you look through the steps in the Pattern log to confirm which nodetool error you are getting:PRB1581285 Cassandra Distributed DB pattern - IRE payload missing matching attributes - Unable to correctly identify the path to nodetool utilityPRB1634965 Cassandra Distributed DB pattern - IRE payload missing matching attributes - nodetool: Failed to connect to '127.0.0.1:7199' - FailedLoginException: 'Required key 'username' is missing'."Steps to Reproduce Install Discovery and Service Mapping Patterns 1.0.96On the target server, install Cassandra, and have JDK 8u331 or above installed.Do not patch for CASSANDRA-17581Discovery the host Actual behaviour: Run the pattern will show the error 'Malformed IPv6 address at index 7: rmi://[127.0.0.1]:7199' in the pattern log for several steps starting with the "Get Cluster Name" step (sa_discovery_log).This results in the pattern Erroring at the Payload Processing step. Discovery log (discovery_log) will give an IRE error: Update failed with error: Commit was not attempted due to other errors.,In payload missing minimum set of input values for criterion (matching) attributes from identify rule for table [cmdb_ci_cassandra_instance]. Add these input values in payload item '{"className":"cmdb_ci_cassandra_instance"... Expected behaviour: Pattern should collect all the attributes from nodetool (uid and name) and have no errors.WorkaroundThis problem is currently under review and targeted to be fixed in a future release.
