.bashrc文件显示错误

Question

I am using linux mint 17.2 64bit rafaela cinnamon edition . I configured hadoop 2.7.1 successfully but after a system restart it is showing errors. I have installed oracle jdk1.8. These are my hadoop's hduser .bashrc file values.

# 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 --#

And The version is

 Hadoop 2.7.1
 Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r

 Compiled with protoc 2.5.0
 From source with checksum fc0a1a23fc1868e4d5ee7fa2b28a58a
 This command was run using /usr/local/hadoop/share/hadoop/common 
 /hadoop-   common-2.7.1.jar

while login to hduser the terminal shows error that shown below

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

I got every needed component at the first time i put 'jps' command but after OS restart the 'jps' command returns the following value only

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

Let me know the configuration problem I am new to linux

Answer 1

Remove the space at line 12: export YARN_HOME = $HADOOP_HOME .

export YARN_HOME=$HADOOP_HOME

bash doesn't like spaces around =

If you want to know on which line number it failes next time, you can paste it in a text file and execute that file with bash file.sh It'll tell you nicely where you need to look.
