[英]Hadoop 2.6 installation on Mac, failed to start ResourceManager
I'm trying to install Hadoop on Mac, following this post. 在这篇文章之后 ,我正在尝试在Mac上安装Hadoop 。
Everything looks fine, but in the end, I cannot start the ResourceManager
. 一切看起来都很好,但是最后,我无法启动
ResourceManager
。 ie after running $jps
. 即在运行
$jps
。
It is supposed to show something like below. 它应该显示类似下面的内容。
2507 ResourceManager ---------this is missing (not started)
1712 SecondaryNameNode
1412 NameNode
1540 DataNode
2045 NodeManager
2858 Jps
Here is the error message I got: 这是我收到的错误消息:
starting resourcemanager, logging to /usr/local/Cellar/hadoop/2.6.0/libexec/logs/yarn-myUserName-resourcemanager-Mac.out
nohup: can't detach from console: No such file or directory nohup:无法从控制台分离:没有这样的文件或目录
FYI, I've also changed the ownership of this hadoop folder. 仅供参考,我还更改了此hadoop文件夹的所有权。 (as follows)
(如下)
$mkdir -p /usr/local/Cellar/hadoop/2.6.0/hadoop_data/hdfs/namenode
$mkdir -p /usr/local/Cellar/hadoop/2.6.0/hadoop_data/hdfs/datanode
$sudo chown -R Tiger /usr/local/Cellar/hadoop
Any suggestions? 有什么建议么?
that's wired, I just retried to start the resourcemanager, it works !!!! 有线,我只是尝试启动resourcemanager,它有效!!!! thought the nodemanager stoped.
以为节点管理器停止了。 sorry for bothering, Omigo
抱歉,Omigo
