any thought how resolve error?

ok got problem solved.

since using single-node cluster through network proxy, had added next property line $hadoop_home/conf/mapred-site.xml by-pass proxy server while communicating across hadoop daemons.

however, time trying out on direct net connection, had comment out property added in mapred-site.xml.

below property mapred-site.xml commented out:

<!-- <property> <name>hadoop.rpc.socket.factory.class.default</name> <value>org.apache.hadoop.net.standardsocketfactory</value> <final>true</final> <description> prevent proxy settings set clients in job configs affecting our connectivity. </description> </property> -->
