             Summary: Caching tables containing boolean, binary, array, struct and/or map columns doesn't work
                 Key: SPARK-4182
                 URL: https://issues.apache.org/jira/browse/SPARK-4182
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.1.1
            Reporter: Cheng Lian
            Priority: Blocker


If a table contains a column whose type is binary, array, struct, map, and for some reason, boolean, in-memory columnar caching doesn't work because a {{NoopColumnStats}} is used to collect column statistics. {{NoopColumnStats}} returns an empty statistics row, and thus breaks {{InMemoryRelation}} statistics calculation.
