一、准备工作
1.1 前言
这是博主在升级过程中遇到的问题记录，大家不一定遇到过，如果不是 CDH 平台的话，单是 hive 服务升级应该是不会有这些问题的，且升级前博主也参考过几篇相关 CDH 升级 hive 服务的博文，前面的升级步骤基本一致，但是升级过程只有我遇到了这些问题吗？显然不是的，但是其他博文都未提及出现过的问题以及如何处理和排查，特别是当升级完之后 hive metastore 无法启动的问题，相信很多人也会遇到如下错误：
#典型错误1
Class "org.apache.hadoop.hive.metastore.model.MDatabase" field "org.apache.hadoop.hive.metastore.model.MDatabase.createTime" : declared in MetaData, but this field doesnt exist in the class!
org.datanucleus.metadata.InvalidClassMetaDataException: Class "org.apache.hadoop.hive.metastore.model.MDatabase" field "org.apache.hadoop.hive.metastore.model.MDatabase.createTime" : declared in MetaData, but this field doesnt exist in the class!
#典型错误2
Class "org.apache.hadoop.hive.metastore.model.MVersionTable" field "org.apache.hadoop.hive.metastore.model.MVersionTable.schemaVersionV2" : declared in MetaData, but this field doesnt exist in the class!
org.datanucleus.metadata.InvalidClassMetaDataException: Class "org.apache.hadoop.hive.metastore.model.MVersionTable" field "org.apache.hadoop.hive.metastore.model.MVersionTable.schemaVersionV2" : declared in MetaData, but this field doesnt exist in the class!
#其他错误可看博主下面的记录内容单拎出来这些报错，度娘多多少少还是可以找到一些类似的解决方案，不过经过博主测试，都不能解决出现的问题，因此才有了此篇博文，当然最后也完美解决了所有问题，不保证后面使用过程中是否会出现问题，因为还没有进一步测试，但是升级和使用，是没有问题的。
请大家一定看完整篇再进行实际操作，过程中有些点是踩坑的，没必要去进行！！！

From source with checksum 75df142c785df1d0b37a9d40fe16169f1.3 停止 hive 服务
1.4 获取资源
下载hive包： 官网下载：Downloads
#解压
[root@hadoop105 soft]# tar -zxvf apache-hive-3.1.3-bin.tar.gz
[root@hadoop105 soft]# mv apache-hive-3.1.3-bin /opt/cloudera/hive二、升级操作
2.1 修改相关配置
#修改jar包
#复制 jar 包目录
[root@hadoop105 soft]# cp -r /opt/cloudera/parcels/CDH/lib/hive/lib /opt/cloudera/parcels/CDH/lib/hive/lib313
#删除 hive 开头的 jar 包
[root@hadoop105 soft]# cd /opt/cloudera/parcels/CDH/lib/hive/lib313/
[root@hadoop105 lib313]# rm -rf ./hive-*.jar
#将解压出来的 hive 包中 hive 开头的 jar包复制进去
[root@hadoop105 lib313]# cp /opt/cloudera/hive/lib/hive-*.jar ./#修改启动文件
[root@hadoop105 lib313]# vi /opt/cloudera/parcels/CDH/lib/hive/bin/hive
#HIVE_LIB=${HIVE_HOME}/lib #注释
HIVE_LIB=${HIVE_HOME}/lib313 #新增2.2 升级元数据库
注意：尽量一步一步升级，不要跳着升级，不然可能会失败
这里升级包含了（upgrade-2.1.0-to-2.2.0.mysql.sql、upgrade-2.2.0-to-2.3.0.mysql.sql、upgrade-2.3.0-to-3.0.0.mysql.sql、upgrade-3.0.0-to-3.1.0.mysql.sql）
[root@hadoop105 lib313]# cd /opt/cloudera/hive/scripts/metastore/upgrade/mysql/
#因为我的 hive 和 mysql 不在同一个节点上，因此需要把升级文件拷贝到 mysql 节点上
[root@hadoop105 mysql]# scp ./* root@192.168.0.106:/opt/hive_sql
[root@hadoop106 hive_sql]# chown mysql /opt/hive_sql/*
#升级
[root@hadoop106 ~]# cd /opt/hive_sql
[root@hadoop106 ~]# mysql -uroot -p
mysql> use hive；
#升级到2.2.0
mysql> source upgrade-2.1.0-to-2.2.0.mysql.sql;

*** schemaTool failed ***大致原因是：这里看到连接的是：Connecting to jdbc:derby:;databaseName=metastore_db;create=true，我们是myql 不是derby，而我初始化的时候已经指定了 db 类型为 mysql：-dbType mysql
处理：可以尝试如下方法：
/etc/hive/conf/hive-site.xml
/etc/hive/conf/hive-default.xml
/opt/cloudera/parcels/CDH/lib/hive/conf/hive-site.xml
/opt/cloudera/parcels/CDH/lib/hive/conf/hive-default.xml
#在上面这些文件中找到 javax.jdo.option.ConnectionURL 属性 进行修改正确的类型
如果都没有，那么修改 /etc/hive/conf/hive-site.xml 增加如下配置并保存：
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>

*** schemaTool failed ***问题：发现还是报 APP 用户的问题，兜兜转转，突然想起来我的配置文件里并没有指定用户，所以默认才用了app用户。
处理：我们在 hive-site.xml 加入如下配置指定 root 用户

*** schemaTool failed ***问题：因为在初始化过程中重复插入了具有相同主键的行而导致的。在这种情况下，主键是 'org.apache.hadoop.hive.metastore.model.MNotificationLog'，并且已经存在于表中，因此无法再次插入。
处理：删除重复主键
#删除重复主键
mysql> DELETE FROM mysql.metastore WHERE UUID = 'org.apache.hadoop.hive.metastore.model.MNotificationLog';
ERROR 1146 (42S02): Table 'mysql.metastore' doesn't exist
#没有表信息
mysql> SHOW TABLES FROM mysql;
#确认 mysql 库确实没有metasotre表
#创建metasotre表
mysql> CREATE TABLE mysql.metastore (
-> UUID VARCHAR(128) NOT NULL,
-> -- add other columns here
-> PRIMARY KEY (UUID)
-> );
Query OK, 0 rows affected (0.01 sec)
#重新执行初始化
====略====问题：如果又报 Error: Table 'CTLGS' already exists
处理：把该表 drop 掉 或者 删除掉 hive 数据库，再重新创建一次，前提是做好备份，然后再执行初始化。
#建议两个同时执行，不然没完没了
mysql> DROP TABLE CTLGS;
Query OK, 0 rows affected (0.00 sec)
mysql> DELETE FROM mysql.metastore WHERE UUID = 'org.apache.hadoop.hive.metastore.model.MNotificationLog';
Query OK, 0 rows affected (0.00 sec)最后重新执行一次初始化（这次初始化已没有错误项），重启 cdh hive 服务
以上到此解决了元数据初始化的问题
（4）重启 cdh 的 hive 服务
虽然重启过程中没有出现问题，但是实际 Hive Metastore Server 启动后会自动退出，查看 hive 日志：/var/log/hive/hadoop-cmf-hive-HIVEMETASTORE-hadoop105.log.out

过程到这里，也说明了和 mysql 的 jar 包没有关系，以上纯属实验过程，如果实际操作，可忽略替换 mysql jar 包这个问题。
那么有可能是不是 hive merastore 版本和 mysql 的 hive 不一致导致的？可以通过以下命令查到的版本是3.1.3了，而且也重新初始化过几次 hive 元数据了呀

Hive 3.1.3
Git git://MacBook-Pro.fios-router.home/Users/ngangam/commit/hive -r 4df4d75bf1e16fe0af75aad0b4179c34c07fc975
Compiled by ngangam on Sun Apr 3 16:58:16 EDT 2022
From source with checksum 5da234766db5dfbe3e92926c9bbab2af考虑是不是因为用了旧的 hive-site.xml 配置的问题，我重新把升级的 hive-3.1.3 的 模板配置文件给替换了旧的 hive-site.xml ，但是依然是同样的报错，到这里基本上该测试的都测试了，似乎没有办法了。。。
------------------------------------------------------此处是转折点---------------------------------------------------------
（6）执行文件的替换
那么单独在 shell 命令行启动 hive metastore 和 hiveserver2 呢？
/opt/cloudera/parcels/CDH/lib/hive/bin/hive --service metastore#发现报错一样是
Class "org.apache.hadoop.hive.metastore.model.MVersionTable" field "org.apache.hadoop.hive.metastore.model.MVersionTable.schemaVersionV2" : declared in MetaData, but this field doesnt exist in the class!
org.datanucleus.metadata.InvalidClassMetaDataException: Class "org.apache.hadoop.hive.metastore.model.MVersionTable" field "org.apache.hadoop.hive.metastore.model.MVersionTable.schemaVersionV2" : declared in MetaData, but this field doesnt exist in the class有没有一种可能是 bin 下有些配置也需要变更呢？于是
#备份原来的bin目录
[root@hadoop105 hive]# mv bin bin_bak
#将之前解压hive-3.1.3的hive下的bin目录拷贝过来使用
[root@hadoop105hive]# mv /opt/cloudera/hive/bin ./#然后尝试启动 hive metastore
[root@hadoop33 bin]# ./hive --service metastore

（7）恢复日志打印
仔细查看 hive 可执行文件的内容，看到有个环境文件是有被引入的，即：hive-env.sh，通过查找可以发现文件是：/etc/hive/conf.cloudera.hive/hive-env.sh
[root@hadoop105 bin]# find / -name hive-env.sh
/run/cloudera-scm-agent/process/ccdeploy_hive-conf_etchiveconf.cloudera.hive_-3511402930136781029/hive-conf/hive-env.sh
/run/cloudera-scm-agent/process/ccdeploy_hive-conf_etchiveconf.cloudera.hive_-8778661946554121081/hive-conf/hive-env.sh
/run/cloudera-scm-agent/process/ccdeploy_hive-conf_etchiveconf.cloudera.hive_-6400195964492722735/hive-conf/hive-env.sh
/etc/hive/conf.cloudera.hive/hive-env.sh###编辑文件，把/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/hive/lib 都要改成：/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/hive/lib313
###这也是为什么用cdh平台去启用hive服务时，/var/log/hive/hadoop-cmf-hive-HIVEMETASTORE-hadoop33.log.out 不输出日志的原因

处理：为了避免还有其他影响，我再次删掉库信息，并重新初始化

（8）替换相关服务 jar 包
部分服务需要依赖于 hive 的，也同样需要将相关的 jar 包进行替换，如spark。
#替换spark包
[root@hadoop105 ~]# cd /opt/cloudera/parcels/CDH/lib/spark
[root@hadoop105 spark]# mv hive hive2.1.1
[root@hadoop105 spark]# mkdir hive
[root@hadoop105 spark]# cp /opt/cloudera/parcels/CDH/lib/hive/lib313/hive-exec-3.1.3.jar hive/2.4 注意项
注意：CDH 的相关服务一般不会只有一个节点，hive metastore server 服务和 hiveserver2 服务可能有多个节点，每个节点的 hive/lib 和 hive/bin 都要进行替换。
三、总结
总结的大致过程就是：停止服务》备份数据》修改配置(替换lib和bin)》升级元数据库》初始化元数据》修改cdh环境配置》重启hive
