> Currently S3GuardTool is operating against a S3AFileSystem implementation. 
> There are cases where the {{fs.hboss.fs.s3a.impl}} is a FilterFileSystem 
> wrapping another implementation. For example, [[HBASE-23314]] made 
> {{HBaseObjectStoreSemantics}} a {{FilterFileSystem}} from {{FileSystem}}. 
> S3GuardTool could use {{FilterFileSystem::getRawFileSystem}} method to get 
> the wrapped S3AFileSystem implementation. Without this support, a simple 
> S3GuardTool against HBOSS will get confusing error like "s3a://mybucket is 
> not a S3A file system".
