I have already have a standalone ignite cluster running on k8s and can run SQL statements against it fine.
Part of a requirements on the system i am building is to perform v-pivots on the query result set. I've seen spark come up as a good solution to v-pivots and so I'm trying to set up a simple master + executor cluster. I have added all the ignite libs to the classpath per the docs but when i attempt to launch the master i get the error: Error SparkUncaughtExceptionHandler:91 - Uncaught Exception in thread Thread[main,5,main] java.io.IOException: failure to login Caused by: javax.security.auth.login.LoginException: java.lang.NullPointerException: invalid null input: name Any pointers on what I am doing incorrectly? I dont have a separate HDFS cluster to log in to, I just want to use spark over the ignite caches.
