> Key: HDFS-15423

> Priority: Major

> Time Spent: 4h
> Remaining Estimate: 0h
>
> In {{RouterWebHdfsMethods}} and for a {{CREATE}} call, {{chooseDatanode}}
> first gets all DNs via {{getDatanodeReport}}, and then randomly pick one from
> the list via {{getRandomDatanode}}. This logic doesn't seem correct as it
> should pick a DN for the specific cluster(s) of the input {{path}}.
