Summary: RBF:Improving StateStoreZookeeperImpl
Key: HDFS-16848
URL: https://issues.apache.org/jira/browse/HDFS-16848
Project: Hadoop HDFS
Issue Type: Improvement
Components: rbf
Reporter: Sun Hao
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。
