> Make initial sleeptime in locateFollowingBlock configurable for DFSClient.
> Current the sleeptime/localTimeout in locateFollowingBlock/completeFile from
> DFSOutputStream is hard-coded as 400 ms, but retries can be configured by
> "dfs.client.block.write.locateFollowingBlock.retries". We should also make
> the initial sleeptime configurable to give user more flexibility to control
> both retry and delay.
