> We have a cold data cluster, which stores as EC policy. There are 24 fast 
> disks on each node and each disk is 7 TB. 
> Recently, many nodes have more than 10 million blocks, and the interval of 
> FBR is 6h as default. Frequent FBR caused great pressure on NN.

> We want to increase the interval of FBR, but have to rolling restart the DNs, 
> this operation is very heavy. In this scenario, it is necessary to make 
> _dfs.blockreport.intervalMsec_ reconfigurable.
