> 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.
