> {code}
> And I know that Scanning blocks on volume and then calculating the dfsUsed
> costs the most of time. Because my datanode's migiration costs the much time,
> so that dfsUsed value can't use cache-dfsused and should be doing du
> operations. But actually I don't need do it again because there has no
> operations in these datanodes. The info is these:
> {code}
> /**
> * Read in the cached DU value and return it if it is less than 600 seconds
> * old (DU update interval). 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.
> * */
> {code}
> The 600 seconds is a dead code. And it looks not suitable for here.
