YARN and Map-reduce example error

[qiyuangong]

Reason:

1. “smart.server.rpc.address” not configured after deploying SSM’s jars. Please check configuration in CDH.
2. SSM not started after deploying SSM’s jars. We have found key point of this issue, and are working on it. (Will patch to release-1.3.2 and trunk this week).

Command example:

sudo -u hdfs hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi -Dmapred.job.queue.name=root.production.streaming 3 3

Running map-reduce example in command line raise errors:

java.net.ConnectException: Call From bb-node3/192.168.1.103 to localhost:7042 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/Co
