alamb opened a new issue #817:
URL: https://github.com/apache/arrow-datafusion/issues/817
**Describe the bug**
The tests in the `datafusion-examples` fail after upgrade to arrow 5.1.0
(they worked on 5.0.0).
I believe the issue is some incompatible version of tonic -- the 5.1.0
release updated tonic
**To Reproduce**
```
cargo update # <-- critical to get arrow 5.1.0 update
cargo test --all
```
Results in these failures:
```

**Expected behavior**
All tests pass
