CDH-5.14.2集群升级Hive-1.1.0至Hive-1.2.1
参考：
CDH 5.1.5(parcels)集群中hive1.1.0升级到hive-1.2.1步骤全，升级hive元数据库，数据不丢失（亲测可用）
操作步骤：
下载hive-1.2.1-bin
解压：
[root@node01 ~]# cd /opt/software/
[root@node01 software]# ls
apache-hive-1.2.1-bin.tar.gz cloudera-manager-centos7-cm5.14.2_x86_64.tar.gz jdk-8u231-linux-x64.tar.gz maxwell-1.22.1.tar.gz
apache-phoenix-4.14.0-cdh5.14.2-bin.tar.gz flink-1.9.1-cdh-5.14.2.tar.gz kafka-manager-1.3.1.6.zip mysql-connector-java.jar
[root@node01 software]# tar -zxf apache-hive-1.2.1-bin.tar.gz -C /opt/module/
[root@node01 software]# cd /opt/module/
[root@node01 module]# mv apache-hive-1.2.1-bin hive-1.2.1
[root@node01 module]# cd hive-1.2.1/
将hive-1.2.1中的lib复制到cdh中hive的lib121目录下
[root@node01 hive]# cd /opt/cloudera/parcels/CDH/lib/hive
[root@node01 hive]# mkdir lib121
[root@node01 hive]# cp /opt/module/hive-1.2.1/lib/* lib121/
修改cdh中hive启动文件中的hive-lib配置
[root@node01 bin]# pwd
/opt/cloudera/parcels/CDH/lib/hive/bin
[root@node01 bin]# vi hive
......
HIVE_LIB=${HIVE_HOME}/lib121
......
Coudera 界面停止Hive服务，如果安装了Hue，Ozzie，Impala先停掉再停掉Hive
所有节点更新hadoop上jline jar包，并删除老的jlien jar包
[root@node01 lib121]# ln -s /opt/cloudera/parcels/CDH/lib/hive/lib121/jline-2.12.jar /opt/cloudera/parcels/CDH/lib/hadoop-yarn/lib/jline-2.12.jar
[root@node01 lib121]# cd /opt/cloudera/parcels/CDH/lib/hadoop-yarn/lib/
[root@node01 lib]# ls

分发到所有节点，更改所属用户、用户组
chown -R cloudera-scm:cloudera-scm /opt/cloudera
在元数据存储所在节点备份MySQL中hive元数据库：
[root@node02 ~]# mysqldump -uroot -hnode02 -p metastore > metastore110.sql
执行升级脚本：
[root@node02 hive-1.2.1]# cd /opt/module/hive-1.2.1/scripts/metastore/upgrade/mysql/
[root@node02 mysql]# mysql -uroot -p
