can retrive FS metadata from slaves?

I know The NameNode is a Single Point of Failure for the HDFS Cluster, When
the meta in NameNode goes down, all data in filesystem is destroy.
Without consideration of any backup of metadata.

question: is it valuable to implement retrive metadata from the block report
from the slaves?

just something in my mind.
