If the Metadata Access Service is inactive for a long time and you import a Hive, HBase, MapR-DB, or complex file data object, the import might fail with the following error:
Workaround: Restart the Metadata Access Service and import the object again.
When you import a complex file object, an HBase object, or a Hive object from a Hadoop cluster, the metadata import fails if the domain and the Metadata Access Service use Kerberos authentication.
Workaround: Contact Informatica Global Customer Support.
The JMX server's use of random selection for its listening port results in a vulnerability.
When the JMX server starts, it randomly chooses a port to listen for requests, and re-chooses a random port whenever the domain restarts. Because of this, administrators cannot know the port in advance, and must apply security measures manually each time the domain restarts.
Workaround: To address this issue, use a utility such as netstat to identify the open ports, and then apply security measures, such as instituting an IP address filter.
You must repeat this process each time the node process or service process restart.
