> We met two issues when using balancer.
> # Moving hot files may cause failing of dfsclient reading.
> # Some blocks of temporary files are moved and they are deleted soon.
> Add a config key " dfs.namenode.hot.block.time.interval", the balancer
> prefer to get the blocks which are belong to the cold files created before
> this time period.
> Also add a option "-hotBlockTimeInterval" to the command line of balancer for
> inputting.
