hadoop hive中metastore报错的解决

报的错：

Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

解决办法：　把metastore的相关配置设置为空就ｏｋ了．
我修改后的配置：

<property>
  <name>hive.metastore.metadb.dir</name>
  <value></value>
  <description>The location of filestore metadata base dir</description>
</property>

<property>
  <name>hive.metastore.uris</name>
  <value></value>
  <description>Comma separated list of URIs of metastore servers. The first server that can be connected to will be used.</description>
</property>

<property>
  <name>hive.metastore.warehouse.dir</name>
  <value></value>
  <description>location of default database for the warehouse</description>
</property>
