Todd Lipcon resolved HDFS-340.
------------------------------

    Resolution: Not A Problem

This was resolved somewhere along the line with an undocumented config parameter.

>                 Key: HDFS-340
>                 URL: https://issues.apache.org/jira/browse/HDFS-340
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>            Reporter: Arun C Murthy

> 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?
