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？
我已经安装了hadoop 2.6.0,我正在玩它.我正在尝试伪分布式设置,我正按照http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html#Execution上的说明 我被卡住了在第5步,即当我运行命令时
bin/hdfs dfs -put etc/hadoop input
我得到以下错误.
15/02/02 00:35:49 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
put: `input': No such file or directory
为什么我收到此错误？我该如何解决？
我使用本教程在一台机器上安装了Hadoop 2.2:http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/
一些细节有点改变 - 例如,我使用java 8,/ hadoop root dir等用户,SSH,配置密钥 - 相同.
