hive启动hiveserver2连JDBC报错：Could not open client transport with JDBC Uri解决方案

开启hiveserver2和beeline后jdbc报错Could not open client transport with JDBC Uri

0: jdbc:hive2://hadoop100:10000（closed）> 

报错信息

Error: Could not open client transport with JDBC Uri: jdbc:hive2://hadoop100:10000/hive_metadata;user=hadoop: java.net.ConnectException: 拒绝连接 (Connection refused) (state=08S01,code=0)
Beeline version 2.3.3 by Apache Hive

解决方案：

在hadoop文件core-site.xml中配置信息如下，重启HDFS和Yarn，再次启动hiveserver2和beeline即可

<property>
    <name>hadoop.proxyuser.hadoop.hosts</name>
    <value>*</value>
</property>
<property>
    <name>hadoop.proxyuser.hadoop.groups</name>
    <value>*</value>
</property>

ok，hive的jdbc连接正常了

beeline> !connect jdbc:hive2://hadoop100:10000
