Hi Arun,

 Here NameNode is in safe mode. This is not related to permission problem. It looks to me
that you have synced some blocks and restarted NN. So, NN will expect some blocks to come
out of safemode. But in your version of hadoop, that partial blocks will not be reported again
from DN. or DN did not send blk reports yet (in ideal case.)
If you dont have any useful data in cluster, can you please format once and restrat again?

Hope, it should work.

Regards,
Uma
