Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "GettingStartedWithHadoop" page has been changed by GlenMazza: http://wiki.apache.org/hadoop/GettingStartedWithHadoop?action=diff&rev1=31&rev2=32 Comment: Short circuiting the reader to the more up-to-date Hadoop website if case he/she was unaware of the tutorials there. ## page was renamed from Getting Started With Hadoop ## page was renamed from GettingStartedWithHadoop + + Note: for the 1.0.x series of Hadoop the following articles will probably be easiest to follow: + + * [[http://hadoop.apache.org/docs/stable/single_node_setup.html|Hadoop Single-Node Setup]] + * [[http://hadoop.apache.org/docs/stable/cluster_setup.html|Hadoop Cluster Setup]] + + The below instructions are primarily for the 0.2x series of Hadoop. + = Downloading and installing Hadoop = Hadoop can be downloaded from one of the [[http://www.apache.org/dyn/closer.cgi/hadoop/|Apache download mirrors]]. You may also download a [[http://people.apache.org/builds/lucene/hadoop/nightly/|nightly build]] or check out the code from [[http://lucene.apache.org/hadoop/version_control.html|subversion]] and build it with [[http://ant.apache.org|Ant]]. Select a directory to install Hadoop under (let's say {{{/foo/bar/hadoop-install}}}) and untar the tarball in that directory. A directory corresponding to the version of Hadoop downloaded will be created under the {{{/foo/bar/hadoop-install}}} directory. For instance, if version 0.21.0 of Hadoop was downloaded untarring as described above will create the directory {{{/foo/bar/hadoop-install/hadoop-0.21.0}}}. The examples in this document assume the existence of an environment variable {{{$HADOOP_INSTALL}}} that represents the path to all versions of Hadoop installed. In the above instance {{{HADOOP_INSTALL=/foo/bar/hadoop-install}}}. They further assume the existence of a symlink named {{{hadoop}}} in {{{$HADOOP_INSTALL}}} that points to the version of Hadoop being used. For instance, if version 0.21.0 is being used then {{{$HADOOP_INSTALL/hadoop -> hadoop-0.21.0}}}. All tools used to run Hadoop will be present in the directory {{{$HADOOP_INSTALL/hadoop/bin}}}. All configuration files for Hadoop will be present in the directory {{{$HADOOP_INSTALL/hadoop/conf}}}.
