Lukas Majercak updated HDFS-14043:
----------------------------------
Description: 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.
