ASF GitHub Bot commented on PARQUET-2153:
-
NilsB44 opened a new pull request, #977:
URL: https://github.com/apache/parquet-mr/pull/977
This extends the previous issue PARQUET-1441, where this issue was fixed for
RecordSchema but not for FixedSchema.
Make sure you have checked _all_ steps below.
### Jira
- [ ] My PR addresses the following [Parquet
Jira](https://issues.apache.org/jira/browse/PARQUET/) issues and references
them in the PR title. For example, "PARQUET-1234: My Parquet PR"
- https://issues.apache.org/jira/browse/PARQUET-XXX
- In case you are adding a dependency, check if the license complies with
the [ASF 3rd Party License
Policy](https://www.apache.org/legal/resolved.html#category-x).
### Tests
- [ ] My PR adds the following unit tests __OR__ does not need testing for
this extremely good reason:
I'm unsure on how to add unit tests for FixedSchema, maybe someone could
help me on this?
### Commits
- [ ] My commits all reference Jira issues in their subject lines. In
addition, my commits follow the guidelines from "[How to write a good git
commit message](http://chris.beams.io/posts/git-commit/)":
1. Subject is separated from body by a blank line
1. Subject is limited to 50 characters (not including Jira issue reference)
1. Subject does not end with a period
1. Subject uses the imperative mood ("add", not "adding")
1. Body wraps at 72 characters
1. Body explains "what" and "why", not "how"
### Documentation
- [ ] In case of new functionality, my PR adds documentation that describes
how to use it.
- All the public functions and the classes in the PR contain Javadoc that
explain what it does

I found out that this is indeed the same issue as for PARQUET-1441, however for
FixedSchema. The fix is isolated to RecordSchema and the same fix needs to be
applied to FixedSchema as well.
