Bryan Cutler created ARROW-1821:
-----------------------------------
Summary: Add integration test case to explicitly check for
optional validity buffer
Key: ARROW-1821
URL: https://issues.apache.org/jira/browse/ARROW-1821
Project: Apache Arrow
Issue Type: Test
Reporter: Bryan Cutler
Assignee: Bryan Cutler
Fix For: 0.8.0
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.
