我是hadoop map reduce的新手。启动dfs时出现以下错误。

satya@satyaPC:/usr/local/hadoop_store/hdfs/namenode$ start-all.sh

Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar 
15/10/02 20:38:46 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

由于此警告，名称节点和数据节点无法启动。这是jps命令的结果。

satya@satyaPC:/usr/local/hadoop_store/hdfs/namenode$ jps

Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar 

6113 Jps

5755 ResourceManager

6077 NodeManager

5592 SecondaryNameNode

我尝试使用以下链接修复它：http://www.csrdu.org/nauman/2014/01/23/geting-started-with-hadoop-2-2-0-building/ 但这导致了以下错误。

satya@satyaPC:/usr/local/hadoop/protobuf-2.5.0$ make install
