+## Setup Hadoop Benchmark
+
+Here are my steps. First, checkout hadoop 2.10.0 binary, untar, and cd in to the hadoop directory.
+```
+wget http://apache.mirrors.hoobly.com/hadoop/common/hadoop-2.10.0/hadoop-2.10.0.tar.gz
+tar xvf hadoop-2.10.0.tar.gz
+cd hadoop-2.10.0
+```
+
+Modify the file `./etc/hadoop/core-site.xml`
+
+```
+<configuration>
+    <property>
+        <name>fs.seaweedfs.impl</name>
+        <value>seaweed.hdfs.SeaweedFileSystem</value>
+    </property>
+    <property>
+        <name>fs.defaultFS</name>
+        <value>seaweedfs://localhost:8888</value>
+    </property>
+</configuration>
+```
+
+Then get the seaweedfs hadoop client jar.
+
+```
+cd share/hadoop/common/lib/
+wget https://oss.sonatype.org/service/local/repositories/releases/content/com/github/chrislusf/seaweedfs-hadoop2-client/1.3.2/seaweedfs-hadoop2-client-1.3.2.jar
+```
+
+Start the TestDFSIO tests:
+
+```
+bin/hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-2.10.0-tests.jar TestDFSIO -write -nrFiles 64 -fileSize 16GB -resFile /tmp/TestDFSIOwrite.txt
+
+...
