> On startup, the NN reads the fstime file of all the configured dfs.name.dirs to determine
which one to load. However, if any of the searched directories contain an empty or malformed
fstime file, the NN will fail to start. The NN should be able to just proceed with starting
and ignore the directory containing the bad fstime file.
