 ====== MapReduce Tutorial : Setting Eclipse ======
-TODO. Muzu Te Martine poprosit?
+//This is not well tested.//
+If you do not like VIM, you can try using Eclipse as a Java editor. You should
+  - Download ''/SGE/HADOOP/active/hadoop-core-1.0.1-SNAPSHOT.jar''
+  - Download the directory ''/net/projects/hadoop/java-extensions/classes''
+  - Create a new Eclipse project that references the ''hadoop-core-1.0.1-SNAPSHOT.jar'' and includes all the files in ''/net/projects/hadoop/java-extensions/classes''.
+  - The jar file must be copied to the UFAL cluster to be executed. If you have to input your password for every ''ssh'' login, you can use connection sharing and input password only once -- see [[step-22#Connection sharing]].
+===== Instructions =====
+==== Remote Execution ====
+  * Download Eclipse project on shared file system
+  wget 'http://ufallab.ms.mff.cuni.cz/~majlis/eclipse-project.tar.gz'
+  tar -xzf eclipse-project.tar.gz
+  * Execute Eclipse (ufal-computer = gaia, osiris, mrblack, ...)
+  ssh -X -Y ufal-computer.ms.mff.cuni.cz '/home/majlis/bin/eclipse'
+  * In Eclipse create new project (File > New > Java Project)
+    * Select //Create project from existing source// and browse to location, where files were extracted.
+==== Local Execution ====
+  * On your local computer execute the following commands:
+  wget 'http://ufallab.ms.mff.cuni.cz/~majlis/eclipse-project.tar.gz'
+  tar -xzf eclipse-project.tar.gz
+  * Execute Eclipse ( Applications > Programming > Eclipse 3.5.1 )
+  * In Eclipse create new project (File > New > Java Project)
+    * Select //Create project from existing source// and browse to location, where files were extracted.
+===== Connection sharing =====
+If you need to type password every time you login to UFAL network, you can use connection sharing to write it only once:
+  * execute ''ssh -N -M -S ~/.ssh/master-%l-%r@%h:%p geri''.
+  * while the previous ''ssh'' is running, you can use ''ssh -S ~/.ssh/master-%l-%r@%h:%p geri'' to log in ''geri'' without password.
