Name node not starting after computer restarts

Hello,

 

My cluster has the following configuration  2 NN , 5 DN , 3 JN.

After restarting the cluster ,none of the name node started .Please see the attached screenshot & logs.

Is there any suggestion to start the name node ? This is DEV enviroment,so if i lost the data i can easily reload it.

 

Thanks
