My core-site.xml file contains this:

    <property>
       <name>fs.=

       <value>hdfs://localhost:9000</value>

My .profile(replacement for .bashrc) contains these lines:

export JAVA_HOME=3D/usr/lib/jvm/java-= 7-openjdk-amd64 export HADOOP_INSTALL=3D/usr/local/hadoop export PATH=3D$PA= TH:$HADOOP_INSTALL/bin export PATH=3D$PATH:$HADOOP_INSTALL/sbin export HADO= OP_MAPRED_HOME=3D$HADOOP_INSTALL export HADOOP_COMMON_HOME=3D$HADOOP_INSTAL= L export HADOOP_HDFS_HOME=3D$HADOOP_INSTALL export YARN_HOME=3D$HADOOP_INST= ALL export HADOOP_COMMON_LIB_NATIVE_DIR=3D$HADOOP_INSTALL/lib/native export= HADOOP_OPTS=3D"-Djava.library.path=3D$HADOOP_INSTALL/lib"

And I can easily ssh my localhost saying:
