報錯環境：

CDH中集成的hive服務，啟動報錯，所以初始化一下元數據。

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：

執行以下命令的時候報錯：

./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文件中添加以下內容

<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>

保存之后重新執行命令。
