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?
