Hi Yes I did configure using the wiki link at http://wiki.apache.org/hadoop/EclipseEnvironment. I am facing a new problem while setting up Hadoop in Psuedo-distributed mode on my laptop. I am trying to execute the following commands for setting up Hadoop: hdfs namenode -format hdfs namenode hdfs datanode yarn resourcemanager yarn nodemanager
It gives me a "Hadoop Common not found." error for all the commands. When I try to use "hadoop namenode -format" instead, it gives me a deprecated command warning. I am following the instructions for setting up Hadoop with Eclipse given in - http://wiki.apache.org/hadoop/HowToSetupYourDevelopmentEnvironment - http://hadoop.apache.org/common/docs/r2.0.0-alpha/hadoop-yarn/hadoop-yarn-site/SingleCluster.html This issue is discussed in JIRA < https://issues.apache.org/jira/browse/HDFS-2014 > and is resolved. Not sure why I am getting the error. My environment variables look something like: HADOOP_COMMON_HOME=/home/Projects/hadoop-common/hadoop-common-project/hadoop-common/target/hadoop-common-3.0.0-SNAPSHOT HADOOP_CONF_DIR=/home/Projects/hadoop-common/hadoop-common-project/hadoop-common/target/hadoop-common-3.0.0-SNAPSHOT/etc/hadoop HADOOP_HDFS_HOME=/home/Projects/hadoop-common/hadoop-hdfs-project/hadoop-hdfs/target/hadoop-hdfs-3.0.0-SNAPSHOT HADOOP_MAPRED_HOME=/home/Projects/hadoop-common/hadoop-mapreduce-project/target/hadoop-mapreduce-3.0.0-SNAPSHOT YARN_HOME=/home/Projects/hadoop-common/hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-common/target/hadoop-yarn-common-3.0.0-SNAPSHOT YARN_CONF_DIR=/home/Projects/hadoop-common/hadoop-mapreduce-project/hadoop-yarn/conf I have included them in the PATH. I am trying to build and setup from apache-hadoop-common git repository (my own cloned fork). Any idea why 'Hadoop Common Not found' error is coming? Do I have to add anything to the hadoop-config.sh or hdfs-config.sh?
