Hello everybody,

          Earlier I was getting an issue while running the c++ binaries in hadoop

 syscon@syscon-OptiPlex-3020:~/uday/hadoop-1.2.1$ bin/hadoop pipes -D hadoop.pipes.java.recordreader=true -D hadoop.pipes.java.recordwriter=true -input /dft1 -output dft1 -program /bin/wordcount

在上述几次失败的尝试之后，它将终止：

注意：我已经在我的电脑上安装了libssl.so…但是它仍然抛出错误。。。
我需要在配置文件中更改哪些内容才能使其正常工作？
有人能帮我吗？
