I have derived a dataframe from oracle using Sqlcontext and I have registered it as temp table tb1.

I have another dataframe which is derived from hive using HiveContext and I registered this as table tb2.

When I am trying to access these two tables using HiveContext I am getting the error like Unable to find tb1 and when try it with sqlcontext.

I am getting error like Unable to find tb2.

Any help on this please.

I'm doing it in Scala of-course.

please post your code – Arunakiran Nulu Oct 23 '16 at 03:50
If you created separate `HiveContext` and `SQLContext` - you shouldn't - HiveContext extends SQLContext so it has all of its abilities. Create a single HiveContext _only_ and use it to create both tables. – Tzach Zohar Oct 23 '16 at 07:58
