Dear Wiki user, You have subscribed to a wiki page or wiki category on "Lucene-hadoop Wiki" for change notification.
The following page has been changed by aranud: http://wiki.apache.org/lucene-hadoop/GettingStartedWithHadoop The comment on the change is: fixed typo ------------------------------------------------------------------------------ = Downloading and installing Hadoop = - Hadoop can be downloaded from one of the [http://www.apache.org/dyn/closer.cgi/lucene/hadoop/ Apache download mirrors]. You may also download a [http://cvs.apache.org/dist/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 0.6.0 of Hadoop was downloaded untarring as described above will create the directory {{{/foo/bar/hadoop-install/hadoop-0.6.0}}}. 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 verision 0.6.0 is being used then {{{$HADOOP_INSTALL/hadoop -> hadoop-0.6.0}}}. All tools used to run Hadoop will be present in the directory {{{$HADOOP_INSTALL/hadoop/bin}}}. All configuration files for Hadoop will be present in the directory {{{$HADOOP_INSTALL/hadoop/conf}}}. + Hadoop can be downloaded from one of the [http://www.apache.org/dyn/closer.cgi/lucene/hadoop/ Apache download mirrors].
