export PATH=$JAVA_HOME/bin/:$JRE_HOME/bin/:$PATH
export HADOOP_HOME=/home/xyz/hadoop/hadoop-2.7.0
export PATH=$HADOOP_HOME/bin/:$PATH
export PATH=$HADOOP_HOME/sbin/:$PATH:/home/xyz/hive/apache-hive-1.2.1-bin/bin/
export LD_LIBRARY_PATH=$HADOOP_HOME/lib/native/:$LD_LIBRARY_PATH
export JAVA_LIBRARY_PATH=$HADOOP_HOME/lib/native/
export HADOOP_PREFIX=$HADOOP_HOME

我的/etc/profile文件是这么配的 # set java environment export JAVA_HOME=/usr/java/jdk1.8.0_151 export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

jdk版本低了会有问题，用jdk1.8试试

这一看就是你的hadoop的java环境配置错了
