Cheng Lian created SPARK-4182:
---------------------------------
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.
