Quick Start

Checking out Hadoop: Git:

mkdir hadoop-git ; cd hadoop-git

git clone https://github.com/apache/hadoop-common.git
git clone https://github.com/apache/hadoop-hdfs.git
git clone https://github.com/apache/hadoop-mapreduce.git

(or if we fix ssh: #git clone git://git.apache.org/hadoop-common.git
#git clone git://git.apache.org/hadoop-mapreduce.git
#git clone git://git.apache.org/hadoop-hdfs.git
)

svn:

mkdir hadoop-svn ; cd hadoop-svn
svn co https://svn.apache.org/repos/asf/hadoop/common/trunk
svn co https://svn.apache.org/repos/asf/hadoop/mapreduce/trunk
svn co https://svn.apache.org/repos/asf/hadoop/hdfs/trunk
(for trunk -- for branches, use /repos/asf/hadoop/common/branches/branch-0.22 )

Running tests

ant test-core -Dtest.output=yes -Dtestcase=TestEditLog

test.output will print output to console, useful for hanging tests

Eclipse: see EclipseEnvironment
