HiveTableRelation Assertion Error | Joining Stream with Hive table

Hi,

I have a dataframe reading messages from kafka topic. I have another
dataframe created from a hive table. When I join (inner) stream with hive
table i am getting below assertion error.

java.lang.AssertionError: assertion failed: No plan for HiveTableRelation

When i do an explain on the joined dataframe i get following error.

java.lang.UnsupportedOperationException: LeafNode StreamingRelation must
implement statistics.

Any hints to resolve this issue would be helpful.

I am using spark 2.2.0 version

Thanks,
Manjunath
