-Use https://github.com/sakserv/hadoop-mini-clusters
+#Usage
+##Integration testing (will start each component present into classpath)
+With maven, add dependencies of components which are needed
 
-Need : https://github.com/jetoile/hadoop-bootstrap-test-utils
+Sample:
+```xml
+<dependency>
+    <groupId>fr.jetoile.hadoop</groupId>
+    <artifactId>hadoop-unit-hdfs</artifactId>
+    <version>1.1-SNAPSHOT</version>
+    <scope>test</scope>
+</dependency>
+```
+
+In test do:
+```java
+@BeforeClass
+public static void setup() {
+    HadoopBootstrap.INSTANCE.startAll();
+}
+
+@AfterClass
+public static void tearDown() {
+    HadoopBootstrap.INSTANCE.stopAll();
+}
+```
+
+##WIntegration testing v2 (with specific component)
+With maven, add dependencies of components which are needed
+
+Sample:
+```xml
+<dependency>
+    <groupId>fr.jetoile.hadoop</groupId>
+    <artifactId>hadoop-unit-hdfs</artifactId>
+    <version>1.1-SNAPSHOT</version>
+    <scope>test</scope>
+</dependency>
+```
+
+In test do:
+```java
+@BeforeClass
+public static void setup() throws NotFoundServiceException {
+    HadoopBootstrap.INSTANCE
+        .start(Component.ZOOKEEPER)
+        .start(Component.HDFS)
+        .start(Component.HIVEMETA)
+        .start(Component.HIVESERVER2);
+}
+
+@AfterClass
+public static void tearDown() throws NotFoundServiceException {
+    HadoopBootstrap.INSTANCE
+        .stop(Component.HIVESERVER2)
+        .stop(Component.HIVEMETA)
+        .stop(Component.HDFS)
+        .stop(Component.ZOOKEEPER);
+}
+```
+
+##Standalone mode
+Unzip hadoop-unit-standalone-<version>.tar.gz
+Change `conf/default.properties`
+Change `conf/hadoop.properties`
+
+Start in fg with:
+```bash
+./bin/hadoop-unit-standalone console
+```
+
+Start in bg with:
+```bash
+./bin/hadoop-unit-standalone start
+```
+
+Stop with:
+```bash
+./bin/hadoop-unit-standalone stop
+```
+
+#Sample
+See hadoop-unit-standalone/src/test/java/fr/jetoile/hadoopunit/integrationtest
+
+#Component available
+
+* SolrCloud 5.4.1
+* Kafka 0.9.0
+* Hive (metastore and server2)
+* Hdfs
+* Zookeeper
+* Oozie (WIP)
+* HBase
+
+Built on:
+
+* hadoop-mini-cluster-0.1.3 (0.1.4 not released on central maven repo) (https://github.com/sakserv/hadoop-mini-clusters)
+
+Use: 
+* download and unzip hadoop
+* download and unzip oozie (http://s3.amazonaws.com/public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.3.4.0/tars/oozie-4.2.0.2.3.4.0-3485-distro.tar.gz)
+* edit default.properties and indicate HADOOP_HOME
+* edit default.properties and indicate oozie.sharelib.path
+
+Todo:
+* male client utils for kafka produce/consume
+* make sample with spark streaming and kafka
+
+Issues:
+* oozie does not work on windows 7 (see http://stackoverflow.com/questions/25790319/getting-access-denied-error-while-running-hadoop-2-3-mapreduce-jobs-in-windows-7)
+* integrate phoenix
+* can only manage one solr collection
+* better docs ;)
