.

Root cause: Keystore file was corrupted.

.

Resolution: Move the corrupted files to a temp directory and restart Knox. Knox will create the files again and restart will be successful.

ssh knoxhost
mkdir /tmp/keystores
mv /usr/hdp/current/knox-server/data/security/keystores/* /tmp/keystores

Hope this helps 🙂
