Question

我已经使用CDH4.1安装了配置单元我想使用MySql进行hive Metastore，我编辑了hive-site.xml以配置mysql并启动了hive服务器和Metastore 当我试图在蜂巢中创建表时，它显示以下错误 FAILED：元数据错误：java.lang.RuntimeException：无法实例化org.apache.hadoop.hive.metastore.HiveMetaStoreClient FAILED：执行错误，从org.apache.hadoop.hive.ql.exec.DDLTask返回代码1 有人可以帮忙吗？我尝试使用以下帖子FAILED: Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

解决

我的hive-site.xml如下

    <property> 
      <name>javax.jdo.option.ConnectionURL</name>
     <value>jdbc:hive2://localhost:21050/;auth=noSasl</value>
     <description>the URL of the MySQL database</description>
    </property>

     <property>
    <name>javax.jdo.option.ConnectionDriverName</name>
    <value>com.mysql.jdbc.Driver</value>
     </property>

   <property>
   <name>javax.jdo.option.ConnectionUserName</name>
   <value>hive</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>Newuser123</value>
</property>

<property>
  <name>datanucleus.autoCreateSchema</name>
  <value>false</value>
</property>
<property>
  <name>datanucleus.fixedDatastore</name>
  <value>true</value>
</property>

<property>
  <name>hive.metastore.uris</name>
  <value>thrift://localhost:9083</value>
  <description>IP address (or fully-qualified domain name) and port of the metastore host</description>
</property>

一个可能的原因是连接到Hive的数据库（MySql）尚未启动。开始：

/etc/init.d/mysqld start

在配置单元中创建表时出错
