Work Description: viirya opened a new pull request #3385:
URL: https://github.com/apache/hadoop/pull/3385
Lz4 is a provided dependency. So in the shaded Hadoop libraries, e.g.
hadoop-client-api, if we don't exclude lz4 dependency from relocation, the
downstream will still see the exception even they include lz4 dependency.
```
