Bryan Cutler resolved SPARK-22534.
----------------------------------
Resolution: Not A Problem
Opened by mistake
> Add integration test case to explicitly verify optional validity buffer
> -----------------------------------------------------------------------
>
> Key: SPARK-22534
> URL: https://issues.apache.org/jira/browse/SPARK-22534
> Project: Spark
> Issue Type: Test
> Components: Tests
> Affects Versions: 0.8.0
> Reporter: Bryan Cutler
>
> When the null count of a Field is 0 the validity buffer is optional in a
> RecordBatch message. From ARROW-1476, integration tests were failing because
> of this (see discussion here
> https://github.com/apache/arrow/pull/1316#issuecomment-344439955). The
> failure occurred due to chance of the random seed for generating the validity
> buffer. We should explicitly test this case for integration testing in the
> future.
