Hi, we are trying to configure an integration between trino, spark and hive metastore (HMS) in a secure way.
Hive metastore has already been configured in order to use kerberos and TLS. Trino has already been configured in order to connect to HMS using TLS and kerberos. Trying to do the same for spark (connect it to HMS using TLS and kerberos) we faced a problem with TLS connection: if we configure spark using kerberos and plain connection to HMS (reconfiguring HMS too) it works, but if we enable TLS on both, spark is not able to connect. The error on HMS is the following: "Caused by: javax.net.ssl.SSLException: Unsupported or unrecognized SSL message" and indeed connections initiated by spark are alway plain. spark: 3.5.2_scala2.12 hadoop: 3.3.6 iceberg: 1.6.0 hive: 4.0.0 spark conf: https://gist.github.com/bovy89/83cbe3b9cd7a318fa9fd35355d5801fc Any ideas?
