Hadoop Pipes程序运行Server failed to authenticate错误解决

julley

　　运行hadoop自带的pipes examples没有问题,自己写个却在jobtracker界面中报了Server failed to authenticate. Exiting错误.去日志中看下,完整异常如下:
　　1.job日志

　　2.task日志

　　看来是权限的问题,那为什么我运行hadoop自带的pipes example就不会有问题呢？如此应该是环境方面的问题了.于是跑到$HADOOP_HOME/src/examples/org/pipes中的Makefile.in和configure看到的hadoop环境是默认的/usr/local/include和/usr/local/lib(前提是pipes，libhdfs,utils等已经安装).而我自己用c++写的mapreduce所配置的hadoop编译环境是$HADOOP_HOME/c++/include和$HADOOP_HOME/c++/lib，这个是hadoop默认的。于是改下自己的hadoop编译环境,发现便可以正常运行。
　　这里也有一篇解决方法,但针对的是你用hadoop自带的pipes example也报这个错误。则需要采用这个方法了。http://www.linuxquestions.org/questions/linux-software-2/hadoop-1-0-3-pipes-server-failed-to-authenticate-4175429779/。英文的,同时为了防止被删除或者被墙,我这里也记录下。
　　1.在/etc/profile添加一个变量,命令如下：
　　export LIB=-lcrypto
　　2.修改$HADOOP_HOME/src/contrib/gridmix/src/java/org/apache/hadoop/mapred/gridmix/Gridmix.java:
　　patch如下：

Index: src/contrib/gridmix/src/java/org/apache/hadoop/mapred/gridmix/Gridmix.java

sb.append(v.name());

　　3.安装c++/utils,到$(HADOOP_HOME)/src/c++/utils运行如下命令:

./configure
make install
　　4.安装c++/pipes,到$(HADOOP_HOME)/src/c++/pipes运行如下命令:

./configure
make install
　　5.再你的Makefile中使用如下设置:

-I$(HADOOP_HOME)/src/c++/install/include
-L$(HADOOP_HOME)/src/c++/install/lib -lhadooputils -lhadooppipes -lcrypto -lssl -lpthread
　　或者你不用修改你的Makefile,只要将$(HADOOP_HOME)/src/c++/install下的东西替换到$HADOOP_HOME/c++即可.
