cdh4中的hadoop和hive家庭

我正在尝试在cdh4环境中配置rhive。读取r中的包“rhive”时，返回下面的错误。我猜那是因为错误的家庭。如果是的话，正确的答案是什么？或者如果这不是原因，那又有什么错呢？
任何帮助都将不胜感激。
谢谢。

> Sys.setenv(HADOOP_HOME="/etc/hadoop")

This is RHive 0.0-7. For overview type '?RHive'.
HIVE_HOME=/etc/hive
[1] "there is no slaves file of HADOOP. so you should pass hosts argument when you call rhive.connect()."

您应该分别设置hadoop\u conf\u dir。请尝试导出$hadoop\u conf\u dir=/etc/hadoop/conf/conf.pseudo
conf.pseudo包含从属文件。
不过我很好奇你能不能让rhive和cdh4一起工作。

Had the problems but solved it. Downside is that I have to keep track of a bunch of sym links

After struggling with install RHive_0.0-7.tar.gz on CDH 4.7.x and getting: 
Warning in file(file, "rt") :
cannot open file '/etc/hadoop/conf/slaves': No such file or directory
[1] "there is no slaves file of HADOOP. so you should pass hosts argument when you call rhive.connect()."

In /etc/hadoop/conf
I added a the following sym link ----> ln -s /opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/etc/hadoop/conf.empty/slaves slaves
(why Cloudera CHD 4.7 installs in /opt without creating the proper sym links from /usr/lib is puzzling)

I also defined the followingin /usr/lib64/R/etc/Renviron

## set hive paths

HIVE_HOME='/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hive'
HADOOP_HOME='/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hadoop'
LD_LIBRARY_PATH='/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hadoop'

At a shell prompt I ran R CMD INSTALL RHive_0.0-7.tar.gz 
Installation Happiness!!

This is RHive 0.0-7. For overview type ‘?RHive’.
HIVE_HOME=/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hive
call rhive.init() because HIVE_HOME is set.
rhive.init()
