Why the cluster stays at State: INITIALIZING
Hi everyone
Why my cluster always show:State: INITIALIZING for a long time after I
execute start-all.sh
Is there any thing wrong with my configuration? Or mainly because of the
safe mode on the below webpage
Any body can help me?

If there is some critical writes to be done, you can force the cluster out
of safe mode.
hadoop dfsadmin -safemode leave
Considering your ratio of reported blocks and if you have a replication
factor of 3 it should be fine to force exit out of safe mode. (But always
better to wait for auto exit from safe mode)

there MUST some datanodes cannot start, so blocks cannot reach the thresh
hold. please check which data nodes cannot start, then check data node log.
