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

報錯環境：

CDH中集成的hive服務，啓動報錯，因此初始化一下元數據。

配置文件：/etc/hive/conf hive-site.xml

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

報錯現象：

執行如下命令的時候報錯：

./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 ***

解決方法：

在hive-site.xml文件中添加如下內容

<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>

保存以後從新執行命令。
