Review comment:
Hopefully not because of the
[`Optional.ofNullable`](https://docs.oracle.com/javase/8/docs/api/java/util/Optional.html#ofNullable-T-).

> Re-enable optimized copyFromLocal implementation in S3AFileSystem
> -----------------------------------------------------------------

> Key: HADOOP-17139
> URL: https://issues.apache.org/jira/browse/HADOOP-17139
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0, 3.2.1
> Reporter: Sahil Takiar
> Assignee: Bogdan Stolojan

> It looks like HADOOP-15932 disabled the optimized copyFromLocal
> implementation in S3A for correctness reasons. innerCopyFromLocalFile should
> be fixed and re-enabled. The current implementation uses
> FileSystem.copyFromLocal which will open an input stream from the local fs
> and an output stream to the destination fs, and then call IOUtils.copyBytes.
> With default configs, this will cause S3A to read the file into memory, write
> it back to a file on the local fs, and then when the file is closed, upload
> it to S3.
> The optimized version of copyFromLocal in innerCopyFromLocalFile, directly
> creates a PutObjectRequest request with the local file as the input.
