Date Fri, 23 Sep 2011 15:20:04 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "HowToContribute" page has been changed by SteveLoughran:
http://wiki.apache.org/hadoop/HowToContribute?action=diff&rev1=64&rev2=65

  
   * A Java Development Kit is required to be installed and on the path of executables. The
Hadoop developers recommend the Sun JDK.
   * For MapReduce in 0.23+ : [[http://code.google.com/p/protobuf/|protocol buffers]] (see
[[http://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-mapreduce-project/hadoop-yarn/README|YARN
Readme]. The test for this is verifying that {{{protoc}}} is on the command line.
-  * To install and use ProtocolBuffers: A copy of GCC 4.1+. 
+  * To install and use ProtocolBuffers: A copy of GCC 4.1+, make and the rest of the GNU
C++ development chain.
   * The source code of projects that you depend on. Avro, Jetty, Log4J are some examples.
This isn't compulsory, but as the source is there, it helps you see what is going on.
   * The source code of the Java version that you are using. Again: handy.
   * The Java API javadocs.
