Hmm... it might be good to open a Spark bug. Should be easy to create a
repro - basically what you have in the shell session you tried above, but in a
small scala class. (Start session - use it - stop it - remove metastore db -
start new session - try to use it.)
Given that this seems to be a Spark issue, guess we'll go with the test
changes.---
