问题
为什么我不能用用户ubuntu连接到HiverServer2，但是用户hadoop可以吗？
简报
我在作为操作系统的操作系统为Ubuntu 18.04.5 LTS的名称节点的计算机上创建了一个用户hadoop，并建立了具有4个工作线程的Hadoop集群。
Hadoop 3.3.0
Source code repository https://gitBox.apache.org/repos/asf/hadoop.git -r aa96f1871bfd858f9bac59cf2a81ec470da649af
Compiled by brahma on 2020-07-06T18:44Z
Compiled with protoc 3.7.1
From source with checksum 5dc29b802d6ccd77b262ef9d04d19c4
This command was run using /opt/hadoop-3.3.0/share/hadoop/common/hadoop-common-3.3.0.jar
然后，我在集群上的服务器模式下用Derby构建了Hive。
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/hadoop/apache-hive-3.1.2-bin/lib/log4j-slf4j-impl-2.10.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]
Hive 3.1.2

以下是我试图执行的操作。
$ beeline
beeline> !connect jdbc:hive2://master:10000 APP ${password}
当我用hadoop执行时，我收到了成功的消息。
Connecting to jdbc:hive2://master:10000
Connected to: Apache Hive (version 3.1.2)
Driver: Hive JDBC (version 3.1.2)
Transaction isolation: TRANSACTION_REPEATABLE_READ
当我用ubuntu执行时，收到错误消息。
WARN jdbc.HiveConnection: Failed to connect to master:10000
Error: Could not open client transport with JDBC Uri: jdbc:hive2://master:10000:
Failed to open new session: java.lang.RuntimeException:
org.apache.hadoop.ipc.remoteexception(org.apache.hadoop.security.authorize.AuthorizationException):
User: hadoop is not allowed to impersonate APP (state=08S01,code=0)
我尝试按照AuthorizationException: User not allowed to impersonate User中的neeraj修改core-site.xml和hive-site.xml，但仍然收到相同的错误消息。
这就是我添加到core-site.xml和hive-site.xml中的内容。
<!--core-site.xml-->
<!--This addition is done in the master node and every worker-->
<property>
<name>hadoop.proxyuser.hadoop.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hadoop.hosts</name>
<value>*</value>
</property>
<!--hive-stie.xml-->
<property>
<name>hive.server2.enable.doAs</name>
<value>true</value>
<description>Impersonate the connected user,default true.</description>
</property>
