Hi all,
I notice that HiveContext used to have a refreshTable() method, but it doesn’t
in branch-2.0.
Do we drop that intentionally? If yes, how do we achieve similar functionality?
Thanks.

So we definitely need to be careful here. I know you didn't mention it but it
mentioned by others so I would not recommend using LimitedPrivate. I had
started a discussion on Hadoop about some of this due to the way Spark needed
to use some of the Api's.https://issues.apache.org/jira/browse/HA

Here's a JIRA for it: https://issues.apache.org/jira/browse/SPARK-13346
I don't have a great method currently, but hacks can get around it: convert
the DataFrame to an RDD and back to truncate the query plan lineage.

+1 to the general structure of Reynold's proposal. I've found what we do
currently a little confusing. In particular, it doesn't make much sense
that @DeveloperApi things are always labeled as possibly changing. For
example the Data Source API should arguably be one of the most stable
interfaces
Hi Joseph,
Thank you for the link! Two follow up questions
1)Suppose I have the original DataFrame in Tungsen, i.e. catalyst types and
cached in off-heap store. It might be quite useful for iterative workloads due
to lower GC overhead. Then I convert it to RDD and then backto DF. Will the
