Description

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.
