$ HADOOP_HOME已棄用，Hadoop

我試圖在單個節點集羣上安裝Hadoop（我自己的labtop-ubuntu 12.04）。我按照這個教程，並逐行檢查它兩次。 http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/

一切似乎都正確。我設置了所有的core-site.xml，mapred-site.xml，hdfs-site.xml。

當我運行在hduser蘇以下命令：

[email protected]:~$ /usr/local/hadoop/usr/sbin/start-all.sh

我收到以下錯誤：

Warning: $HADOOP_HOME is deprecated. 

starting namenode, logging to /usr/local/hadoop/usr/libexec/../logs/hadoop-hduser-namenode-maziyar-Lenovo-IdeaPad-U300s.out 
cat: /usr/local/hadoop/usr/libexec/../etc/hadoop/slaves: No such file or directory 
cat: /usr/local/hadoop/usr/libexec/../etc/hadoop/masters: No such file or directory

cat: /usr/local/hadoop/usr/libexec/../etc/hadoop/slaves: No such file or directory

我增加了出口HADOOP_HOME_WARN_SUPPRESS = 「TRUE」到hadoop-env.sh和還是一樣的錯誤。

在文件/home/hduser/.bashrc，我想我的錯誤從正在添加我：

# Set Hadoop-related environment variables 
export HADOOP_HOME=/usr/local/hadoop 

# Set JAVA_HOME (we will also configure JAVA_HOME directly for Hadoop later on) 
export JAVA_HOME=/usr/lib/jvm/jdk-7u10-linuxi586/usr/java/jdk1.7.0_10 

# Some convenient aliases and functions for running Hadoop-related commands 
unalias fs &> /dev/null 
alias fs="hadoop fs" 
unalias hls &> /dev/null 
alias hls="fs -ls" 

# If you have LZO compression enabled in your Hadoop cluster and 
# compress job outputs with LZOP (not covered in this tutorial): 
# Conveniently inspect an LZOP compressed file from the command 
# line; run via: 
# 
# $ lzohead /hdfs/path/to/lzop/compressed/file.lzo 
# 
# Requires installed 'lzop' command. 
# 
lzohead() { 
    hadoop fs -cat $1 | lzop -dc | head -1000 | less 
} 

# Add Hadoop bin/ directory to PATH 
export PATH=$PATH:$HADOOP_HOME/usr/sbin

我添加/ usr/sbin目錄的bin目錄，因爲start-all.sh和命令那裏。

我也在bashrc文件中試過「HADOOP_PREFIX」而不是「HADOOP_HOME」，但仍然是同樣的錯誤。

我有這個文件夾在我的hadoop目錄，

[email protected]:/usr/local/hadoop$ ls -lha 
total 20K 
drwxr-xr-x 5 hduser hadoop 4.0K May 30 15:25 . 
drwxr-xr-x 12 root root 4.0K May 30 15:25 ..

drwxr-xr-x 12 hduser hadoop 4.0K Jun 4 21:29 usr 
drwxr-xr-x 4 hduser hadoop 4.0K May 30 15:25 var

我下載了最新版本的Apache的Hadoop的上週：Hadoop的1.1.2-1.i386.rpm

您使用的是什麼版本的hadoop？ – twid

@twid - 看起來像1.1.2 –

你可以通過'hadoop version'獲得版本 – twid
