报错环境:
CDH中集成的hive服务,启动报错,所以初始化一下元数据。
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:
执行以下命令的时候报错:
./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文件中添加以下内容
<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>
保存之后重新执行命令。
