> RBF: Improve StateStoreZookeeperImpl

>                 Key: HDFS-16848
>                 URL: https://issues.apache.org/jira/browse/HDFS-16848
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: rbf
>            Reporter: Sun Hao
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 3.4.0
>
>
> Currently, router is getting/updating state from zk sequentially. It will 
> slowdown router load/update state cache especially for a large cluster or a 
> multi region cluster.
> We propose adding a threadpool to deal with zk state synchronization。
