报错：Exception in thread "main" java.lang.RuntimeException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

Caused by: MetaException(message:Could not connect to meta store using any of the URIs provided. Most recent failure: org.apache.thrift.transport.TTransportException: java.net.ConnectException: Connection refused

分析：无法连接hivemetastore，通常是我们配置了Hive的元数据存储在远端，而启用Hive时又没有提前启动metastore导致的。

解决：启动metastore服务（该命令会占用会话窗口，可以另开窗口，也可以在命令后面加 &）：

$ bin/hive --service metastore

再次启动Hive命令行

$bin/hive
hive (default)> show databases;
OK
default
mydb
Time taken: 0.023 seconds, Fetched: 2 row(s)
