Thanks ! There was a similar problem: Conflicting Jars, but between Hive and Spark. My eventual goal is running Spark with Hive's tables, and having Spark's libraries on my path as well, there were conflicting Jar files. I removed Spark libraries from my PATH and Hive's services (remote metastore) just started all well. For now I am good, but I am just wondering what is the correct way to fix this ? Once I wanna start Spark, I need to include its libraries to the PATH, and the conflicts seems inevitable.
