Hive 报错：java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

在配置好hive后启动报错信息如下：

 [walloce@bigdata-study- hive-0.13.-cdh5.3.6]$ bin/hive

hive的配置hive-site.xml内容如下：

 <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

 <configuration>

hive的配置文件hive-env.sh的内容如下：

 # Set HADOOP_HOME to point to a specific hadoop install directory
 HADOOP_HOME=/opt/modules/cdh/hadoop-2.5.0-cdh5.3.6

 # Hive Configuration Directory can be controlled by:
 export HIVE_CONF_DIR=/opt/modules/cdh/hive-0.13.1-cdh5.3.6/conf

经过报错信息提示分析，可以看出是因为metastore的原因，解决方案有两种：

1、由于配置好以后，metastore服务没有启动。启动metastore：

　　bin/hive --service metastore &

2、如果没有用到hive的metastore服务，可以先注释掉，注释代码如下：

　　

<!--<property>
        <name>hive.metastore.uris</name>
        <value>thrift://bigdata-study-104:9083</value>
        <description>Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.</description>
</property>-->

按照以上步骤处理后，重新启动hive，问题即解决。
