[SPARK-18121][SQL] Unable to query global temp views when hive support is
enabled
## What changes were proposed in this pull request?
Issue:
Querying on a global temp view throws Table or view not found exception.
Fix:
Update the lookupRelation in HiveSessionCatalog to check for global temp
views similar to the SessionCatalog.lookupRelation.
Before fix:
Querying on a global temp view ( for. e.g.: select * from global_temp.v1)
throws Table or view not found exception
After fix:
Query succeeds and returns the right result.
## How was this patch tested?
- Two unit tests are added to check for global temp view for the code path
when hive support is enabled.
- Regression unit tests were run successfully. ( build/sbt -Phive
hive/test, build/sbt sql/test, build/sbt catalyst/test)
