Javadoc

Read in the cached DU value and return it if it is less than cachedDfsUsedCheckTime which is set by dfs.datanode.cached-dfsused.check.interval.ms parameter. Slight imprecision of dfsUsed is not critical and skipping DU can significantly shorten the startup time. If the cached value is not available or too old, -1 is returned.
