> Project: Hadoop HDFS
> Issue Type: Sub-task

>
> As discussed in HDFS-11535, this JIRA adds a new function combining both the
> new and the old chooseRandom methods for better performance.
> More specifically, when choosing a random node with storage type requirement,
> the combined method first tries the old method of blindly picking a random
> node. If this node satisfies, it is returned. Otherwise, the new chooseRandom
> is called, which guarantees to find a eligible node in one call (if there is
> one at all).
