So you’re with different HiveContext instances for the caching. We are not expected to see the cached tables cached with the other HiveContext instance.

AFAIK, cached table only be visible within the same HiveContext, you probably need to execute the sql query like “cache table mytable as SELECT xxx” in the JDBC connection also.

Hello there, I have a JBDC connection setup to my Spark cluster but I cannot see the tables that I cache in memory. The only tables I can see are those that are in my Hive instance. I use a HiveContext to register a table and cache it in memory. How can I enable my JBDC connection to query this in memory table? Brandon
