关于hadoop的classpath问题

请教一个问题：我开始安装了hadoop hbase hive 然后hive有问题，我就换了一个hadoop版本。但是这一换，namenode和resourcemanager都启动不起来了，昨天在论坛里问了后发现hadoop读取了我并没有启动的hbase里的jar包，今天我把hbase文件夹改名后然后清理tmp文件夹，重新格式化后再启动就一切正常了。
hadoop classpath
/home/spark/hbase/lib/*:/home/spark/hadoop/contrib/capacity-scheduler/*.jar:/home/spark/hadoop/etc/hadoop:/home/spark/hadoop/share/hadoop/common/lib/*:/home/spark/hadoop/share/hadoop/common/*:/home/spark/hadoop/share/hadoop/hdfs:/home/spark/hadoop/share/hadoop/hdfs/lib/*:/home/spark/hadoop/share/hadoop/hdfs/*:/home/spark/hadoop/share/hadoop/yarn/lib/*:/home/spark/hadoop/share/hadoop/yarn/*:/home/spark/hadoop/share/hadoop/mapreduce/lib/*:/home/spark/hadoop/share/hadoop/mapreduce/*

我执行hadoop classpath后，为什么会出现hbase的lib文件夹呢？

sudo vim /etc/profile  进入编辑模式


在文件中找到CLASSPATH ，应该是它的配置问题

export JAVA_HOME=/home/hadoop/hadoop/jdk..

export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib$CLASSPATH

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:/home/hadoop/hadoop/hadoop-1.2.1/bin:$PATH
