+##Hadoop version
+Mahout code depends on hadoop-client artifact, with the default version 2.2.0. To build Mahout against to a
+different hadoop version, hadoop.version property should be set accordingly and passed to the build command.
+Hadoop1 clients would additionally require hadoop1 profile to be activated.
+
+The build lifecycle is illustrated below. 
+
 ## Compiling
 
 Compile Mahout using standard maven commands
 
-    # With hadoop-1.2.1 dependency
-    mvn clean install
-
     # With hadoop-2.2.0 dependency
-    mvn -Dhadoop2.version=2.2.0 clean install
-
-Mahout has an extensive test suite which takes some time to run. If you just want to build Mahout, skip the tests like this
+    mvn clean compile
 
     # With hadoop-1.2.1 dependency
-    mvn -DskipTests clean install
+    mvn -Phadoop1 -Dhadoop.version=1.2.1 clean compile
 
-    # With hadoop-2.2.0 dependency
-    mvn -Dhadoop2.version=2.2.0 -DskipTests clean install

-## Packaging
-
-In order to build the mahout jars, run
+    # With hadoop-2.2.0 dependency
+    mvn -DskipTests=true clean package
 
-    mvn clean package
+    # With hadoop-1.2.1 dependency
+    mvn -Phadoop1 -Dhadoop.version=1.2.1 -DskipTests=true clean package
 
-Or to build Mahout against to a hadoop-2 cluster (version 2.2.0, for example), run
 
-    mvn -Dhadoop2.version=2.2.0 clean package
+In order to add mahout artifact to your local repository, run
 
+    # With hadoop-2.2.0 dependency
+    mvn clean install
 
+    # With hadoop-1.2.1 dependency
+    mvn -Phadoop1 -Dhadoop.version=1.2.1 clean install
