hadoop - 无法通过JDBC连接创建Hive表

Question

我在ubuntu上运行Hive2，并尝试通过hive界面和beeline \ jdbc创建表。
我没有问题通过hive界面创建表，但是通过jdbc访问时出现权限被拒绝错误。

 FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:Got exception: org.apache.hadoop.security.AccessControlException Permission denied: user=hive, access=WRITE, inode="/user/hive/warehouse/page_view":cto:supergroup:drwxrwxr-x

从异常中我看到它正在尝试在不存在的目录中创建表(/ user / hive / warehouse / ...)

我的 hive-default.xml具有以下配置:

<property>
    <name>hive.metastore.warehouse.dir</name>
    <value>/usr/local/apache-hive-1.2.1-bin/metastore_db</value>
    <description>location of default database for the warehouse</description>
  </property>
  <property>

  </property>

    </description>
  </property>
  <property>

    <description>

      MetaStore Client socket lifetime in seconds. After this time is exceeded, client
      reconnects on the next MetaStore operation. A value of 0s means the connection
      has an infinite lifetime.

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

  </property>
  <property>

    <value/>
    <description>Name of the hook to use for retrieving the JDO connection URL. If empty, the value in javax.jdo.option.ConnectionURL is used</description>
  </property>
  <property>
    <name>javax.jdo.option.Multithreaded</name>
    <value>true</value>
    <description>Set this to true if multiple threads access metastore through JDO concurrently.</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:derby:;databaseName=/usr/local/apache-hive-1.2.1-bin/metastore_db;create=true</value>
    <description>JDBC connect string for a JDBC metastore</description>
  </property>

那么，为什么要尝试在/ user / hive / warehouse下创建metastore_db？

我的问题是我没有将hive-default.xml.template名称更改为hive-site.xml。
