             Summary: Backport HDFS-9259 "Make SO_SNDBUF size configurable at DFSClient" to branch-2.7
                 Key: HDFS-12823
                 URL: https://issues.apache.org/jira/browse/HDFS-12823
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs, hdfs-client
            Reporter: Erik Krogen
            Assignee: Erik Krogen


Given the pretty significant performance implications of HDFS-9259 (see discussion in HDFS-10326) when doing transfers across high latency links, it would be helpful to have this configurability exist in the 2.7 series. 

Opening a new JIRA since the original HDFS-9259 has been closed for a while and there are conflicts due to a few classes moving.
