Review comment:
Rather then adding new extra property we can also do something like this
```if (!isS3AFileSystem(defaultFSURI, zepConfigURI)) {
this.hadoopConf.set("fs.file.impl", RawLocalFileSystem.class.getName());
}
public boolean isS3AFileSystem(URI defaultFSURI, URI zepConfigURI) {
return defaultFSURI.getScheme().equals(S3A)
|| (StringUtils.isNotEmpty(zepConfigURI.getScheme())
&& zepConfigURI.getScheme().equals(S3A));
}
```
