Description

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.
