---------------------------------
Summary: Exposure to Guava libraries by directly accessing
tableRelationCache in SessionCatalog caused failures
Key: SPARK-20926
URL: https://issues.apache.org/jira/browse/SPARK-20926
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.2.0
Reporter: Reza Safi
Because of shading that we did for guava libraries, we see test failures
whenever those components directly access tableRelationCache in SessionCatalog.
This can happen in any component that shaded guava library. Failures looks like
this:
