我有一个有线问题，到处找，似乎找不到答案。我在一个节点上运行cloudera4.6，并使用本地mysql db作为hivemetastore数据库。我有许多包含数据的配置单元表，可以使用apachehue配置单元ui进行查询。我还可以间歇地从命令行运行查询，以获取
失败：元数据错误：java.lang.runtimeexception:无法示例化org.apache.hadoop.hive.metastore.hivemetastoreclient失败：执行错误，从org.apache.hadoop.hive.ql.exec.ddltask返回代码1
大约一半的时间。当我试图传递.hql到下面这样的配置单元时，我每次都会得到上面的错误。

hive -f test.hql

每当我通过oozie工作流与hive交互时，我也会看到这个错误。我最初有一个postgresql本地元存储数据库，它也有类似的错误。
下面是我的hive-site.xml。任何帮助摆脱这个错误将不胜感激。
