While trying out JDK 17 with the latest version of Trino (390), we noticed the following. Just thought of sharing in case others come across similar challenges.

  1. Hive catalogs with Kerberos authentication were found to be not using the strong encryption and so we had to add the following flag in krb5.conf file to allow the old configuration to work.
    allow_weak_crypto = true
    (More details - https://stackoverflow.com/questions/70774313/jdk-17-java-17-kerberos-authentication-fail)

  2. Our custom Ranger plugin was using nashorn javascript engine for policy evaluation and this javascript engine is deprecated in JDK 17. We are trying out graalvm.
