> We already tolerate IOExceptions when reading seen_txid file from namenode's
> dirs. So we take the maximum txid of all the *readable* namenode dirs. We
> should extend this to when the file is corrupted. Currently,
> PersistentLongFile.readFile throws NumberFormatException in this case and the
> whole NN crashes.
