我使用的是linux mint 17.2 64位rafaela肉桂版。我成功地配置了hadoop2.7.1，但是在系统重新启动之后，它显示了错误。我已经安装了oraclejdk1.8。这些是我的hadoop的hduser.bashrc文件值。

# Set JAVA_HOME (we will also configure JAVA_HOME directly for Hadoop later on)

 # Add Hadoop bin/ directory to PATH
 # --hadoop enviroment variable starts --#
export HADOOP_HOME=/usr/local/hadoop
export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export PATH=$PATH:$HADOOP_HOME/bin
export PATH=$PATH:$HADOOP_HOME/sbin
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME = $HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"
export PATH=$PATH:/usr/local/hadoop/bin/

# --hadoop enviroment variable end --#

版本是

Hadoop 2.7.1
 Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r 
 15ecc87ccf4a0228f35af08fc56de536e6ce657a
 Compiled by jenkins on 2015-06-29T06:04Z
 Compiled with protoc 2.5.0

 This command was run using /usr/local/hadoop/share/hadoop/common 
 /hadoop-   common-2.7.1.jar

当登录到hduser时，终端显示如下所示的错误

Password: 
bash: export: `=': not a valid identifier
bash: export: `/usr/local/hadoop': not a valid identifier

我在第一次输入'jps'命令时得到了所有需要的组件，但在操作系统重启后，'jps'命令只返回以下值

hduser@vishnu-300E5E-300E4E-300E5V-300E4V ~ $jps
3727 Jps
hduser@vishnu-300E5E-300E4E-300E5V-300E4V ~ $

让我知道配置问题，我是linux新手
