Github user HeartSaVioR commented on the issue: https://github.com/apache/spark/pull/22952 @gaborgsomogyi @steveloughran OK. I'll change the approach to just check against final path for each moving. As @steveloughran stated, it may bring performance hit for each checking when dealing with object stores, so we may also need to provide a way to disable checking as well with caution. (Btw, if moving file in object store requires huge overhead rather than globing, slow globing may not be a big deal.
