[jira] Created: (HADOOP-5132) Allow MAX_XCEIVER_COUNT to be configured

Allow MAX_XCEIVER_COUNT to be configured
----------------------------------------

                 Key: HADOOP-5132
                 URL: https://issues.apache.org/jira/browse/HADOOP-5132
             Project: Hadoop Core
          Issue Type: Improvement
          Components: dfs
    Affects Versions: 0.20.0
            Reporter: Arun C Murthy
             Fix For: 0.21.0


Currently DataXcieverServer.java hardcodes MAX_XCEIVER_COUNT to 256. 

I ran a randomwriter with 4k maps and output replication set to 40 - all write pipelines failed since each DataNode hit the above limit and refused connections.

Should we consider making it configurable?
