CDH5.0.2升级至CDH5.2.0

升级需求
1.为支持spark kerberos安全机制
2.为满足impala trunc函数
3.为解决impala import时同时query导致impala hang问题
升级步骤
参考http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/installation_upgrade.html
优先升级cloudera manager，再升级cdh
1.准备工作：
统一集群root密码，需要运维帮忙操作下
agent自动重启关闭
事先下载好parcals包

2.CM升级
登录cmserver安装的主机，执行命令：
cat /etc/cloudera-scm-server/db.properties
备份CM数据：
  pg_dump -U scm -p 7432   > scm_server_db_backup.bak
  检查/tmp下是否有文件生成，期间保证tmp下文件不要被删除。
停止CM server :
  sudo service cloudera-scm-server stop
停止CM server依赖的数据库：
  sudo service cloudera-scm-server-db stop
如果这台CM server上有agent在运行也停止：
  sudo service cloudera-scm-agent stop
修改yum的 cloudera-manager.repo文件：
  sudo vim /etc/yum.repos.d/cloudera-manager.repo
   [cloudera-manager]
       # Packages for Cloudera Manager, Version 5, on RedHat or CentOS 6 x86_64
       name=Cloudera Manager
       baseurl=http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5/
       gpgkey = http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/RPM-GPG-KEY-cloudera
       gpgcheck = 1
安装：
  sudo
      yum clean all
      sudo yum upgrade 'cloudera-*'
检查：
  rpm  -qa 'cloudera-manager-*'
启动CM server 数据库：
  sudo  service cloudera-scm-server-db start
启动CM server：
  sudo  service cloudera-scm-server start
登录http://172.20.0.83:7180/
  安装agent（步骤略）
升级如果升级jdk，会改变java_home路径，导致java相关服务不可用，需要重新配置java_home
升级CM后需要重启CDH。
3.CDH升级
停止集群所有服务
备份namenode元数据：
  进入namenode dir，执行：
   tar -cvf /root/nn_backup_data.tar ./*
下载parcels
分发包->激活包->关闭（非重启）
开启zk服务
进入HDFS服务->升级hdfs metadata
  namenode上启动元数据
  启动剩余HDFS角色
  namenode响应RPC
  HDFS退出安全模式
备份hive metastore数据库
  mysqldump -h172.20.0.67 -ucdhhive -p111111 cdhhive > /tmp/database-backup.sql
进入hive服务->更新hive metastore
     database scheme
更新oozie sharelib：oozie->install
     oozie share lib
  创建 oozie user
      sharelib
  创建 oozie user
      Dir
更新sqoop:进入sqoop服务->update
     sqoop
  更新sqoop2 server
更新spark（略，可先卸载原来版本，升级后直接安装新版本）
启动集群所有服务：zk->hdfs->spark->flume->hbase->hive->impala->oozie->sqoop2->hue
分发客户端文件：deploy client
     configuration
  deploy hdfs client configuration
  deploy spark client configuration
  deploy hbase client configuration
  deploy yarn client configuration
  deploy hive client configuration
删除老版本包：
  sudo  yum remove bigtop-utils bigtop-jsvc bigtop-tomcat hue-common sqoop2-client
启动agent：
  sudo service cloudera-scm-agent restart
HDFS
  metadata update
  hdfs server->instance->namenode=>action->Finalize
      Metadata Upgrade

升级过程遇主要问题：

原先版本使用了60天试用企业版本，该期限已经过期，升级时Navigator服务启动不了，导致整个cloduera manager server启动失败
升级后问题
a.升级后flume原先提供的第三方jar丢失，需要将包重新放在/opt....下
b.sqoop导入mysql的驱动包找不到，需要将包重新放在/opt....下
c.hbase服务异常

通过cm将safe配置文件里的hbase.rpc.engine org.apache.hadoop.hbase.ipc.SecureRpcEngine去掉后重启成功。
后来发现是cm server的问题，之前修改了一个hostname，cloudera manager server未重启，重启后，加入该配置重启hbase不会有问题。
d.service monitor,zookeeper也有警告，其他服务都有部分红色异常

e.mapreduce访问安全机制下的hbase失败
去除client hbase-site safe配置文件内容：hbase.rpc.protection privacy，旧版本中必须加此配置，而新版本文档中也提到需要加此配置，但经过测试加此配置后报如上异常。

mr中使用http://www.cloudera.com/content/cloudera/en/documentation/cdh5/v5-0-0/CDH5-Installation-Guide/cdh5ig_mapreduce_hbase.html  TableMapReduceUtil.addDependencyJars(job);方式加载。

解决：
hadoop-auth-2.5.0-cdh5.2.0.jar
hive-shims-common-secure-0.13.1-cdh5.2.0.jar
两个包回退版本即可
