> 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
> Assignee: 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.
