I've been experimenting with using PySpark SQL to query Hive tables for the
last week and all has been smooth, but on a command I've run hundreds of
times successfully (a basic SELECT * ...), suddenly this error started
popping up every time I ran a sqlCtx command until I restarted my session.
It's now working again after the restart.
Any idea what this could mean? I'd like to start rolling this out to other
users and would like to be able to help if they run into the same.
An error occurred while calling o33.sql.
