我目前正在运行CentOs的服务器上配置hadoop .当我运行start-dfs.sh或时stop-dfs.sh,我收到以下错误:
WARN util.NativeCodeLoader:无法为您的平台加载native-hadoop库...使用适用的builtin-java类
我正在运行Hadoop 2.2.0.
在线搜索提出了这个链接:http://balanceandbreath.blogspot.ca/2013/01/utilnativecodeloader-unable-to-load.html
但是,/native/hadoop 2.x上的目录内容似乎不同,所以我不知道该怎么做.
我还在这两个环境变量中添加了hadoop-env.sh:
export HADOOP_OPTS ="$ HADOOP_OPTS -Djava.library.path =/usr/local/hadoop/lib /"
export HADOOP_COMMON_LIB_NATIVE_DIR ="/ usr/local/hadoop/lib/native /"
有任何想法吗？
我的目标是在Ubuntu 12.4上运行hadoop 2.2.0.我能够做到但是当我运行以下命令时: rushi @ ubuntu:/ usr/local/hadoop $ sbin/start-dfs.sh
我的dfs正在启动namenode,scondarynamenode和datanode,但问题是我正在遵循警告
rushi@ubuntu:/usr/local/hadoop$ sbin/start-dfs.sh
