停止ambari上服务的顺序
Before performing any upgrades or uninstalling software, stop all of the Hadoop services in the following order: Ranger Knox Oozie WebHCat HiveServer2 Hive Metastore HBase YARN HDFS Zookeeper Storm Kafka Instructions Stop Ranger. Execute the following commands on the Ranger host machine: sudo service ranger-admin stop sudo service ranger-usersync stop Stop Knox. Execute the following command on the Knox host machine. su -l knox -c "/usr/hdp/current/knox-server/bin/gateway.sh stop" Stop Oozie. Execute the following command on the Oozie host machine. su -l oozie -c "/usr/hdp/current/oozie-server/bin/oozied.sh stop" Stop WebHCat. On the WebHCat host machine, execute the following command: su -l hcat -c "/usr/hdp/current/hive-webhcat/sbin/webhcat_server.sh stop" Stop Hive. Execute this command on the Hive Metastore and Hive Server2 host machine. ps aux | awk '{print $1,$2}' | grep hive | awk '{print $2}' | xargs kill >/dev/null 2>&1 Stop HBase Execute this command on all RegionServers: su -l hbase -c "/usr/hdp/current/hbase-regionserver/bin/hbase-daemon.sh stop regionserver" Execute this command on the HBase Master host machine: su -l hbase -c "/usr/hdp/current/hbase-master/bin/hbase-daemon.sh stop master" Stop YARN Execute this command on all NodeManagers: su -l yarn -c "/usr/hdp/current/hadoop-yarn-nodemanager/sbin/yarn-daemon.sh stop nodemanager" Execute this command on the History Server host machine: su -l yarn -c "/usr/hdp/current/hadoop-mapreduce-historyserver/sbin/mr-jobhistory-daemon.sh stop historyserver" Execute this command on the ResourceManager host machine(s): su -l yarn -c "/usr/hdp/current/hadoop-yarn-resourcemanager/sbin/yarn-daemon.sh stop resourcemanager" Stop HDFS Execute this command on all DataNodes: su -l hdfs -c "/usr/hdp/current/hadoop-hdfs-datanode/../hadoop/sbin/hadoop-daemon.sh stop datanode" If you are not running NameNode HA (High Availability), stop the Secondary NameNode by executing this command on the Secondary NameNode host machine: su -l hdfs -c "/usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh stop secondarynamenode" Execute this command on the NameNode host machine(s): su -l hdfs -c "/usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh stop namenode" If you are running NameNode HA, stop the Zookeeper Failover Controllers (ZKFC) by executing this command on the NameNode host machines: su -l hdfs -c "/usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh stop zkfc" If you are running NameNode HA, stop the JournalNodes by executing these commands on the JournalNode host machines: su $HDFS_USER /usr/hdp/current/hadoop-hdfs-journalnode/../hadoop/sbin/hadoop-daemon.sh stop journalnode where$HDFS_USERis the HDFS user. For example,hdfs. Stop ZooKeeper. Execute this command on the ZooKeeper host machine(s): su - zookeeper -c "export ZOOCFGDIR=/usr/hdp/current/zookeeper-server/conf ; export ZOOCFG=zoo.cfg; source /usr/hdp/current/zookeeper-server/conf/zookeeper-env.sh ; /usr/hdp/current/zookeeper-server/bin/zkServer.sh stop" Start Storm services using a process controller, such as supervisord. See "Installing and Configuring Apache Storm" in theManual Install Guide. For example, to stop the storm-nimbus service: sudo /usr/bin/supervisorctl storm-drpc RUNNING pid 9801, uptime 0:03:20 storm-nimbus RUNNING pid 9802, uptime 0:03:20 storm-ui RUNNING pid 9800, uptime 0:03:20 supervisor> stop storm-nimbus storm-nimbus: stopped where$STORM_USERis the operating system user that installed Storm. For example,storm. Stop Kafka. Execute this command on the Kafka host machine(s): su $KAFKA_USER /usr/hdp/current/kafka-broker/bin/kafka stop where$KAFKA_USERis the operating system user that installed Kafka. For example,kafka.
