报错：org.apache.hadoop.hive.metastore.HiveMetaException: Failed to get schema version.

报错环境：

CDH中集成的hive服务，启动报错，因此初始化一下元数据。

配置文件：/etc/hive/conf hive-site.xml

命令目录：/opt/cloudera/parcels/CDH-5.15.1-1.cdh5.15.1.p0.4/lib/hive/bin

报错现象：

执行如下命令的时候报错：

./schematool -dbType mysql -initSchema

[root@master bin]# ./schematool -dbType mysql -initSchema Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0
which: no hbase in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.8.0_191/bin:/root/bin) Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 Metastore connection URL: jdbc:mysql://192.168.52.26:3306/hive
Metastore Connection Driver : com.mysql.jdbc.Driver Metastore connection User: APP org.apache.hadoop.hive.metastore.HiveMetaException: Failed to get schema version. *** schemaTool failed ***

解决方法：

在hive-site.xml文件中添加如下内容

<property>
      <name>javax.jdo.option.ConnectionURL</name>
      <value>jdbc:mysql://192.168.52.26:3306/hive</value>
  </property>
  <property>
      <name>javax.jdo.option.ConnectionDriverName</name>
      <value>com.mysql.jdbc.Driver</value>
  </property>
  <property>
      <name>javax.jdo.option.ConnectionUserName</name>
      <value>root</value>
  </property>
  <property>
      <name>javax.jdo.option.ConnectionPassword</name>
      <value>root</value>
  </property>

保存以后从新执行命令。
