Do you have all DNs running? can you check UI report, wehther all DN are a live?
Can you check the DN disks are good or not?
Can you grep the NN and DN logs with one of the corrupt blockID from below?

Hi Uma,
You are correct, when I start cluster it goes into safemode and if I do wait
its doesn't come out.
I use -safemode leave option.
Safe mode is ON. The ratio of reported blocks 0.0037 has not reached
