> This seems that, somehow the rootdir filesystem is not LocalFileSystem, but
> on HDFS. I have not dig deeper why this happens since it's failing
> intermittently and I can not reproduce it locally. Since this is testing
> export snapshot tool without cluster, we can enforce it using
> LocalFileSystem; no breaking change.
