[转]清理ambari安装的hadoop集群

本文针对redhat或者centos

对于测试集群，若是经过ambari安装Hadoop集群后，想从新再来一次的话，须要清理集群。

对于安装了不少hadoop组件的话，这个工做很繁琐。接下来是我整理的清理过程。

1，经过ambari将集群中的所用组件都关闭，若是关闭不了，直接kill -9 XXX

2，关闭ambari-server，ambari-agent

 

ambari-server stop
ambari-agent stop

 

3，卸载安装的软件

 

yum remove hadoop_2* hdp-select* ranger_2* zookeeper_* bigtop* atlas-metadata* ambari* postgresql spark*  slider* storm* snappy*

 

 

以上命令可能不全，执行完一下命令后，再执行

 

yum list | grep @HDP

 

查看是否还有没有卸载的，若是有，继续经过#yum remove XXX卸载

4，删除postgresql的数据

      postgresql软件卸载后，其数据还保留在硬盘中，须要把这部分数据删除掉，若是不删除掉，从新安装ambari-server后，有可能还应用之前的安装数据，而这些数据时错误数据，因此须要删除掉。

 

rm -rf /var/lib/pgsql

 

5，删除用户

     ambari安装hadoop集群会建立一些用户，清除集群时有必要清除这些用户，并删除对应的文件夹。这样作能够避免集群运行时出现的文件访问权限错误的问题。     

 

userdel oozie
userdel hive
userdel ambari-qa
userdel flume
userdel hdfs
userdel knox
userdel storm
userdel mapred
userdel hbase
userdel tez
userdel zookeeper
userdel kafka
userdel falcon
userdel sqoop
userdel yarn
userdel hcat
userdel atlas
userdel spark
userdel ams

 

 

rm -rf /home/atlas
rm -rf /home/accumulo
rm -rf /home/hbase
rm -rf /home/hive
rm -rf /home/oozie
rm -rf /home/storm
rm -rf /home/yarn
rm -rf /home/ambari-qa
rm -rf /home/falcon
rm -rf /home/hcat
rm -rf /home/kafka
rm -rf /home/mahout
rm -rf /home/spark
rm -rf /home/tez
rm -rf /home/zookeeper
rm -rf /home/flume
rm -rf /home/hdfs
rm -rf /home/knox
rm -rf /home/mapred
rm -rf /home/sqoop

 

6，删除ambari遗留数据

 

rm -rf /var/lib/ambari*
rm -rf /usr/lib/python2.6/site-packages/ambari_*
rm -rf /usr/lib/python2.6/site-packages/resource_management
rm -rf /usr/lib/ambri-*

 

7，删除其余hadoop组件遗留数据

 

 rm -rf /etc/falcon rm -rf /etc/knox rm -rf /etc/hive-webhcat rm -rf /etc/kafka rm -rf /etc/slider rm -rf /etc/storm-slider-client rm -rf /etc/spark rm -rf /var/run/spark rm -rf /var/run/hadoop rm -rf /var/run/hbase rm -rf /var/run/zookeeper rm -rf /var/run/flume rm -rf /var/run/storm rm -rf /var/run/webhcat rm -rf /var/run/hadoop-yarn rm -rf /var/run/hadoop-mapreduce rm -rf /var/run/kafka rm -rf /var/log/hadoop rm -rf /var/log/hbase rm -rf /var/log/flume rm -rf /var/log/storm rm -rf /var/log/hadoop-yarn rm -rf /var/log/hadoop-mapreduce rm -rf /var/log/knox rm -rf /usr/lib/flume rm -rf /usr/lib/storm rm -rf /var/lib/hive rm -rf /var/lib/oozie rm -rf /var/lib/flume rm -rf /var/lib/hadoop-hdfs rm -rf /var/lib/knox rm -rf /var/log/hive rm -rf /var/log/oozie rm -rf /var/log/zookeeper rm -rf /var/log/falcon rm -rf /var/log/webhcat rm -rf /var/log/spark rm -rf /var/tmp/oozie rm -rf /tmp/ambari-qa rm -rf /var/hadoop rm -rf /hadoop/falcon rm -rf /tmp/hadoop rm -rf /tmp/hadoop-hdfs rm -rf /usr/hdp rm -rf /usr/hadoop rm -rf /opt/hadoop rm -rf /opt/hadoop2rm -rf /tmp/hadoop rm -rf /var/hadoop rm -rf /hadoop rm -rf /etc/ambari-metrics-collectorrm -rf /etc/ambari-metrics-monitorrm -rf /var/run/ambari-metrics-collectorrm -rf /var/run/ambari-metrics-monitorrm -rf /var/log/ambari-metrics-collectorrm -rf /var/log/ambari-metrics-monitorrm -rf /var/lib/hadoop-yarnrm -rf /var/lib/hadoop-mapreduce

 

8，清理yum数据源

 

#yum clean all
