简介 在不需要重装操作系统的情况下完全卸载HDP并准备好自动安装HDP2.6的环境。
文章 升级HDP失败后我被迫彻底清除HDP 2.4Ambari 2.5并安装HDP 2.6。 我想避免重新安装操作系统所以执行了如下的步骤。
1、停止在Ambari中的所有服务或杀死他们 可以通过ambari控制台停止所有服务。在我的情况下Ambari在降级时损坏了他的数据库无法启动。 所以我手动杀死所有节点上的所有进程
ps−uhdfs(可以看到所有服务列表) ps -u hdfs (可以看到所有服务列表) kill PID
2、在所有集群节点上运行python脚本
$ python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py –silent –skipusers 3、删除所有节点上的Hadoop包 yum remove hive* yum remove oozie* yum remove pig* yum remove zookeeper* yum remove tez* yum remove hbase* yum remove ranger* yum remove knox* yum remove storm* yum remove accumulo* yum remove falcon* yum remove ambari-metrics-hadoop-sink yum remove smartsense-hst yum remove slider_2_4_2_0_258 yum remove ambari-metrics-monitor yum remove spark2_2_5_3_0_37-yarn-shuffle yum remove spark_2_5_3_0_37-yarn-shuffle yum remove ambari-infra-solr-client 4、删除ambari-server在Ambari主机上和ambari-agent在所有节点上 ambari-server stop ambari-agent stop yum erase ambari-server yum erase ambari-agent 5、删除所有节点上的存储库 rm -rf /etc/yum.repos.d/ambari.repo /etc/yum.repos.d/HDP* yum clean all 6、删除所有节点上的日志文件夹 rm -rf /var/log/ambari-agent rm -rf /var/log/ambari-metrics-grafana rm -rf /var/log/ambari-metrics-monitor rm -rf /var/log/ambari-server/ rm -rf /var/log/falcon rm -rf /var/log/flume rm -rf /var/log/hadoop rm -rf /var/log/hadoop-mapreduce rm -rf /var/log/hadoop-yarn rm -rf /var/log/hive rm -rf /var/log/hive-hcatalog rm -rf /var/log/hive2 rm -rf /var/log/hst rm -rf /var/log/knox rm -rf /var/log/oozie rm -rf /var/log/solr rm -rf /var/log/zookeeper 7、删除所有节点上的Hadoop文件夹包括HDFS数据 rm -rf /hadoop/* rm -rf /hdfs/hadoop rm -rf /hdfs/lostfound rm -rf /hdfs/var rm -rf /local/opt/hadoop rm -rf /tmp/hadoop rm -rf /usr/bin/hadoop rm -rf /usr/hdp rm -rf /var/hadoop 8、删除所有节点上的配置文件夹 rm -rf /etc/ambari-agent rm -rf /etc/ambari-metrics-grafana rm -rf /etc/ambari-server rm -rf /etc/ams-hbase rm -rf /etc/falcon rm -rf /etc/flume rm -rf /etc/hadoop rm -rf /etc/hadoop-httpfs rm -rf /etc/hbase rm -rf /etc/hive rm -rf /etc/hive-hcatalog rm -rf /etc/hive-webhcat rm -rf /etc/hive2 rm -rf /etc/hst rm -rf /etc/knox rm -rf /etc/livy rm -rf /etc/mahout rm -rf /etc/oozie rm -rf /etc/phoenix rm -rf /etc/pig rm -rf /etc/ranger-admin rm -rf /etc/ranger-usersync rm -rf /etc/spark2 rm -rf /etc/tez rm -rf /etc/tez_hive2 rm -rf /etc/zookeeper
9、删除所有节点上的PID
rm -rf /var/run/ambari-agent rm -rf /var/run/ambari-metrics-grafana rm -rf /var/run/ambari-server rm -rf /var/run/falcon rm -rf /var/run/flume rm -rf /var/run/hadoop rm -rf /var/run/hadoop-mapreduce rm -rf /var/run/hadoop-yarn rm -rf /var/run/hbase rm -rf /var/run/hive rm -rf /var/run/hive-hcatalog rm -rf /var/run/hive2 rm -rf /var/run/hst rm -rf /var/run/knox rm -rf /var/run/oozie rm -rf /var/run/webhcat rm -rf /var/run/zookeeper 10、删除所有节点上的库文件夹 rm -rf /usr/lib/ambari-agent rm -rf /usr/lib/ambari-infra-solr-client rm -rf /usr/lib/ambari-metrics-hadoop-sink rm -rf /usr/lib/ambari-metrics-kafka-sink rm -rf /usr/lib/ambari-server-backups rm -rf /usr/lib/ams-hbase rm -rf /usr/lib/mysql rm -rf /var/lib/ambari-agent rm -rf /var/lib/ambari-metrics-grafana rm -rf /var/lib/ambari-server rm -rf /var/lib/flume rm -rf /var/lib/hadoop-hdfs rm -rf /var/lib/hadoop-mapreduce rm -rf /var/lib/hadoop-yarn rm -rf /var/lib/hive2 rm -rf /var/lib/knox rm -rf /var/lib/smartsense rm -rf /var/lib/storm
11、清除所有节点上的文件夹/var/tmp/*
rm -rf /var/tmp/* 12、从cron在所有节点上删除HST /usr/hdp/share/hst/bin/hst-scheduled-capture.sh sync /usr/hdp/share/hst/bin/hst-scheduled-capture.sh
13、删除数据库。 删除MySQL和Postgres的实例以便Ambari安装和配置新的数据库。
yum remove mysql mysql-server yum erase postgresql rm -rf /var/lib/pgsql rm -rf /var/lib/mysql 14、删除所有节点上的符号链接。 尤其是检查文件夹/usr/sbin和/usr/lib/python2.6/site-packages
cd /usr/bin rm -rf accumulo rm -rf atlas-start rm -rf atlas-stop rm -rf beeline rm -rf falcon rm -rf flume-ng rm -rf hbase rm -rf hcat rm -rf hdfs rm -rf hive rm -rf hiveserver2 rm -rf kafka rm -rf mahout rm -rf mapred rm -rf oozie rm -rf oozied.sh rm -rf phoenix-psql rm -rf phoenix-queryserver rm -rf phoenix-sqlline rm -rf phoenix-sqlline-thin rm -rf pig rm -rf python-wrap rm -rf ranger-admin rm -rf ranger-admin-start rm -rf ranger-admin-stop rm -rf ranger-kms rm -rf ranger-usersync rm -rf ranger-usersync-start rm -rf ranger-usersync-stop rm -rf slider rm -rf sqoop rm -rf sqoop-codegen rm -rf sqoop-create-hive-table rm -rf sqoop-eval rm -rf sqoop-export rm -rf sqoop-help rm -rf sqoop-import rm -rf sqoop-import-all-tables rm -rf sqoop-job rm -rf sqoop-list-databases rm -rf sqoop-list-tables rm -rf sqoop-merge rm -rf sqoop-metastore rm -rf sqoop-version rm -rf storm rm -rf storm-slider rm -rf worker-lanucher rm -rf yarn rm -rf zookeeper-client rm -rf zookeeper-server rm -rf zookeeper-server-cleanup
15、删除所有节点上的服务用户
userdel -r accumulo userdel -r ambari-qa userdel -r ams userdel -r falcon userdel -r flume userdel -r hbase userdel -r hcat userdel -r hdfs userdel -r hive userdel -r kafka userdel -r knox userdel -r mapred userdel -r oozie userdel -r ranger userdel -r spark userdel -r sqoop userdel -r storm userdel -r tez userdel -r yarn userdel -r zeppelin userdel -r zookeeper 16、在所有节点上运行find / -name ** 你一定会找到更多的文件/文件夹。 删除它们
find / -name ambari find / -name accumulo find / -name atlas find / -name beeline find / -name falcon find / -name flume find / -name hadoop find / -name hbase find / -name hcat find / -name hdfs find / -name hdp find / -name hive find / -name hiveserver2 find / -name kafka find / -name mahout find / -name mapred find / -name oozie find / -name phoenix find / -name pig find / -name ranger find / -name slider find / -name sqoop find / -name storm find / -name yarn find / -name zookeeper 17、重新启动所有节点 reboot
