Safe mode is the original state of the NameNode until it has a large
enough collection of DataNodes have reported in to have at least 1
copy of at least X% of the blocks. (The default X is 99.9%). I
recommend changing it to 100%. You can force the NameNode to leave
safe mode manually via "bin/hadoop dfsadmin -safemode leave". In safe
mode, the NameNode lets client do read-only operations but not write
operations (including replication decisions).
