Chengwei Wang commented on HDFS-15630:
--------------------------------------
As reported in HDFS-13293, when we try to request mount points with
multi-destinations, the client IP in CallerContext would be wrong.
* the clientIp would duplicate in CallerContext when
RouterRpcClient#invokeSequential.
