Hello, I'm new to Hadoop and i want to learn it in order to do a project. I'v started reading the documentation at this site:
http://hadoop.apache.org/docs/r2.1.0-beta/hadoop-project-dist/hadoop-common/SingleCluster.html for setting a single node, but i could not figure a lot of things in these documentation. 1."You should be able to obtain the MapReduce tarball from the release" I could not find this tarball, where is it. 2."You will need protoc 2.5.0 installed" what is that, there is no even a link for it or what is it 3."Assuming you have installed hadoop-common/hadoop-hdfs" what also are these, and why you are assuming that. i have just downlaod the hadoop-2.1.0-beta<http://ftp.itu.edu.tr/Mirror/Apache/hadoop/common/hadoop-2.1.0-beta/>and extracted it 4. and exported *$HADOOP_COMMON_HOME*/*$HADOOP_HDFS_HOME* !! that is strange, to where should these environment variables indicating lastly as i know,the first step tutorial should give more details. or am i searching the wrong side. ** **
