> Good to know that HMS service takes care of that.
I'm not sure how the HMS manages its credentials, but it'd be good to at least 
verify with a HMS expert that the plugin runs in an environment that does 
periodically re-login.

I looked around the Hive codebase a bit, but not enough to find any background 
re-logins. I did stumble across another MetaStoreEventListener 
https://github.com/apache/hive/blob/48c01107cd18d80867369e5addfa1fc5b4e7f698/hcatalog/server-extensions/src/main/java/org/apache/hive/hcatalog/listener/DbNotificationListener.java
 and I don't see logins, but I'm also not sure if the Hadoop fs APIs they are 
using log in automatically.

PS9, Line 52:
Missed this before. Why don't we want to retry these tests anymore? Should we 
be using a KuduTestHarness here?
