ambari卸载

1.通过ambari将集群中的所用组件都关闭，如果关闭不了，直接kill-9 XXX

2.所有节点运行

# 不同版本位置可能不同
python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py –-silent –-skip=users

3.所有节点删除hadoop包

yum remove -y hadoop_2* hdp-select* ranger* zookeeper* bigtop* atlas-metadata*  spark* slide* strom* hive* ambari* oozie* pig* tez* hbase* knox* storm* accumulo* falcon* smartsense-hst slider*

4.以上命令可能不全，执行完一下命令后，再执行

 rpm –qa|grep Ambari
  rpm –qa|grep ambari

5.关闭ambari-server，ambari-agent

ambari-server stop
