------------------------------------

             Summary: Add clientHostname to RPC header
                 Key: HADOOP-16254
                 URL: https://issues.apache.org/jira/browse/HADOOP-16254
             Project: Hadoop Common

          Components: ipc
            Reporter: He Xiaoqiao
            Assignee: He Xiaoqiao


In order to support data locality of RBF, we need to add new field about client hostname in the RPC headers of Router protocol calls.
 clientHostname represents hostname of client and forward by Router to Namenode to support data locality friendly. See more [^RBF Data Locality Design.pdf] in HDFS-13248 and [maillist vote|http://mail-archives.apache.org/mod_mbox/hadoop-common-dev/201904.mbox/%3CCAF3Ajax7hGxvowg4K_HVTZeDqC5H=3bFB7mV5Sz5MGVadhVjng@mail.gmail.com%3E].
