Known Issues and Workarounds in Cloudera Navigator HSM KMS

Key description is not synchronized with the second metastore

If the description option is specified as the argument in a Hadoop key create command, then the description information is stored only on the KMS instance that responds to the create request. The description metadata is not synchronized to the other KMS instances in the role group. This does not affect normal key operations.

Workaround: Use the -provider argument on the key list operation to target key queries to a specific KMS instance.

Affected Version(s): 5.12.0

Fixed Version: 5.12.1

HSM KMS Luna may need to be restarted if inactive for extended period

If Hadoop key operations return com.safenetinc.luna.exception.LunaCryptokiException after the KMS has been running without activity for an extended period time, the Luna session may have been dropped.

Workaround: Restart the KMS service.

Affected Version(s): 5.12.0

Creating multiple instances of HSM KMS on the same host and port causes an error upon delete

Creating a KMS role instance on a host that previously hosted a KMS role instance in the same role group that had its data directories deleted results in errors when attempting to run Hadoop key delete operations.

Workaround: This workaround requires the assistance of Cloudera support; request assistance with issue KT-4992
