> +Question:+
> Fiware Cosmos Hive Authorization Issue
> +Description:+
> I'm using a shared instance of Fiware Cosmos (meaning I don't have root privileges). I have until today successfully acessed and managed tables in hive both remotely using jdbc, and Hive CLI.
> But now I'm getting this error when starting Hive CLI:
> log4j:ERROR Could not instantiate class [org.apache.hadoop.hive.shims.HiveEventCounter].

> I can however perform select and create in the Hive CLI.
> If I then try to access Hive remotely, I get this:
> Connecting to jdbc:hive://x.x.x.x:10000/default?user=user&password=XXXXXXXXXX
> Could not establish connection: java.net.ConnectException: Connection refused
> I didn't do any changes in code or commands before the errors appeared, and after googling around I haven't found any working solutions. 
> If anyone can guide me to where the problem is, or how to find it, or even better how to solve it, I'd be grateful.
> Thanks in advance!
