    Description

      During the start up, namenode waits for n replicas of each block to be reported by datanodes before exiting the safe mode. Currently n is tied to the min replicas config. We could set min replicas to more than one but we might want to exit safe mode as soon as each block has one replica reported. This can be worked out by introducing a new config variable for safe mode block count
