+  * **KMS encryption using the EMR-EC2 SecretAgent component** – There is an error that occurs when KMS encryption at rest is enabled for Lake Formation-enabled clusters in EMR versions 7.8 and 7.9. Lake Formation-enabled jobs will fail with a _NoSuchMethodError_. There are two workarounds available:
+
+    * Temporarily disable KMS encryption at rest for affected clusters.
+
+    * Contact AWS Support to request a Bootstrap Action artifact if KMS encryption must be maintained.
+
+A permanent fix for this error is being worked on. This release note will be revised when it is deployed.
