CDH问题汇总之——ERROR main:com.cloudera.server.cmf.bootstrap.EntityManagerFactoryBean: Tables have unsuppo

问题描述：

ERROR main:com.cloudera.server.cmf.bootstrap.EntityManagerFactoryBean: Tables have unsupported engine type [MyISAM]. InnoDB is required.

1.查看cm服务运行情况：

service cloudera-scm-server status

  cloudera-scm-server 已死，但 pid 文件仍存  

 

2. 查看日志    
    

vim /var/log/cloudera-scm-server/cloudera-scm-server.log

ERROR main:com.cloudera.server.cmf.bootstrap.EntityManagerFactoryBean: Tables have unsupported engine type [MyISAM]. InnoDB is required.
     数据库要求INNODB

3.修改Mysql数据库引擎

# vim /etc/my.cnf
    
[mysqld]
default-storage-engine=INNODB

#修改后重启
service mysqld restart

4.将Mysql的相关库备份下来（用的Navicat）

5.重新初始化CM库

/usr/share/cmf/schema/scm_prepare_database.sh mysql cm -h127.0.0.1 -uroot -ppasswd --scm-host 127.0.0.1 scm scm scm

6.将Mysql的相关库的数据还原（用的Navicat）

7.重启CM服务

service cloudera-scm-server start
