$_FILES when uploading files, but
magento-connect do not allow to use global variables, and it generates an error in the validation report:
Direct use of $_FILES Superglobal detected

We had the same issue but a little search in the core and also this link helped us figure out the solution
you've to use
$uploader = $this->_objectManager->create( 'Magento\MediaStorage\Model\File\Uploader', ['fileId' => 'my_file_uploader'] );
in place of $_FILES and it's much better like this, you can access various methods in the object. To check the output, use:
this will return an array with details about the file uploaded.
Hope it helps.
