Having a hard time setting-up a single node hadoop 2.2 on Ubuntu 12.04. I'm following this doc: http://hadoop.apache.org/docs/current2/hadoop-project-dist/hadoop-common/SingleCluster.html ( eventhough it is versioned 2.1.1-beta ).
I've setup a dedicated hduser, localhost no pass ssh is setup, JAVA_HOME properly set, Pv6 disabled, and hadoop-2.2.0.tar.gz<http://apache.mirrors.tds.net/hadoop/common/hadoop-2.2.0/hadoop-2.2.0.tar.gz> extracted to /home/hduser/yarn/Hadoop-2.2.0.
The doc starts out with the assumption that hadoop-common/hadoop-hdfs are installed. (I'm assuming that means simply extracting the Hadoop-2.2.tar file since I couldn't find a stand-alone Hadoop-common or Hadoop-hdfs package).
It assumes the following (seems like common sense, but I'll display what I did in case I screwed that up)
$HADOOP_COMMON_HOME - /home/hduser/yarn/Hadoop-2.2.0
$HADOOP_HDFS_HOME - /home/hduser/yarn/Hadoop-2.2.0
$HADOO_MAPRED_HOME - /home/hduser/yarn/Hadoop-2.2.0
$HADOOP_YARN_HOME - /home/hduser/yarn/Hadoop-2.2.0
$HADOOP_CONF_DIR - /home/hduser/yarn/Hadoop-2.2.0/etc/hadoop
untar hadoop mapreduce tarball - hmmm I assume this is the Hadoop-2.2.0 tar file
HDFS should be running. - I'm sure this is trivial to do, but can anybody point out how to do this? In previous versions the Hfile system had be formatted, but the command has apparently been deprecated.
"bin/Hadoop namenode -format" - DEPRECATED: Use of this script to execute hdfs command is deprecated. Instead use the hdfs command for it.
sbin/yarn-daemon.sh start resourcemanager - no visible errors
sbin/yarn-daemon.sh start nodemanager - no visible errors
I'm assuming that the previous two commands don't start every component. I tried the following: sbin/Hadoop-daemon.sh start namenode
But I see the following error:
Java.io.IOException: NameNode is not formatted.
Thanks in advance to anybody that can help me get the single node up and running. Thanks.
