20/11/17 18:53:47 [main]: WARN jdbc.HiveConnection: Failed to connect to hadoop102:10000
Error: Could not open client transport with JDBC Uri: jdbc:hive2://hadoop102:10000: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: root is not allowed to impersonate root (state=08S01,code=0)

解决办法：
在hadoop/etc/core-site.xml下面添加下面的内容，保存
然后重启hdfs

  • stop-dfs.sh
  • start-dfs.sh
<property><name>hadoop.proxyuser.root.groups</name><value>root</value><description>Allow the superuser oozie to impersonate any members of the group group1 and group2</description>
</property>
<property><name>hadoop.proxyuser.root.hosts</name><value>*</value><description>The superuser can connect only from host1 and host2 to impersonate a user</description>
</property>
