I have installed a 4 node Spark-3.3.1 running on YARN. The nodes are: node-master, node1, node2, node3 and node4. I am using JAVA 8.
Spark is working.
I have configured Spark to use 3rd party PKI certificates and successfully created the keystore and truststore. I copied the keystore and truststore to the Spark/conf directory.
I added the following to the spark-defaults.conf file:
spark.ssl.keyPassword key_password (i entered the correct keypassword)
spark.ssl.keyStore /path/to/my_key_store ( i entered the correct path to include the file name)
I then started the spark cluster,
I looked in the log specified when i ran start-master.sh, and this is what the log contained:

Can anyone shed light on the meaning of the warning above? And, why is it spitting out all of the Java 8 ciphers?
Thank you for any guidance/recommendations anyone can provide.
And, just to be complete, i did enter the correct values for the following items in the spark-default.conf file:
Additionally, i copied the keystore and truststore to the node-master. I did not yet copy the keystore and truststore to node1, node2, node3 and node4.
