Hello,
If you use MR3 1.7 on Kubernetes, please update mr3-run-k8s scripts and switch to MR3 1.9. The docker image mr3project/hive3:1.7 uses Java 8, and we will no longer use Java 8 in mr3-run-k8s scripts.
To upgrade to MR3 1.9, updating mr3-run-k8s scripts to the latest commit should be enough.
Cheers,
