      Description

      If the input dir where fair-scheduler.xml / yarn-site.xml sits is the same as the output dir (defined by the -o switch), the fs2cs tool overwrites the source config files, i.e. yarn-site.xml.

      Reproduce this is easy, just run fs2cs tool with this command: 

      /bin/yarn fs2cs --cluster-resource memory-mb=18044928,vcores=16 --no-terminal-rule-check -y yarn-site.xml -f fair-scheduler.xml -o .
      

      The following (or similar) is emitted by the tool:
