JIRA: [HDFS-16331](https://issues.apache.org/jira/browse/HDFS-16331). We have a cold data cluster, which stores as EC policy. There are 24 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.   -- This is an automated message from the Apache Git Service.
