在配置好hive后启动报错信息如下：

hive的配置hive-site.xml内容如下：

hive的配置文件hive-env.sh的内容如下：
1 # Set HADOOP_HOME to point to a specific hadoop install directory 2 HADOOP_HOME=/opt/modules/cdh/hadoop-2.5.0-cdh5.3.6 3 4 # Hive Configuration Directory can be controlled by: 5 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。
