1. metastore配置

 <property>
     <name>hive.metastore.uris</name>
     <value>thrift://111.121.21.23:9083</value>
     <description></description>
</property>

metastore 启动方式

lcc@lcc ~$ hive --service metastore

我们一般用下面连接

HiveConf conf = new HiveConf();
conf.set("hive.metastore.uris", metaStoreUrls);
// 做血缘解析需要的东西
conf.set("hive.exec.post.hooks","org.apache.hadoop.hive.ql.hooks.LineageLogger");
// 有些语法需要的东西
conf.set("hive.exec.dynamic.partition.mode", "nonstrict");
SessionState.start(conf);
LOGGER.info("建立连接hive metastore成功, uris: {}", metaStoreUrls);

使用它获取元数据信息

SessionState.get().setCurrentDatabase(currentDatabase);

2. hiveserver2配置

<property>
       <name>hive.server2.thrift.port</name>
      <value>10002</value>
 </property>

主要是数据库操作

lcc@lcc ~$ beeline -u "jdbc:hive2://lcc:10013"
