authorize.AuthorizationException: User: livy is not allowed to impersonate

部署参考 livy安装:https://cloud.tencent.com/developer/article/1349537

此外需要在hdfs core-site.xml 配置如下代理:


<property>
<name>hadoop.proxyuser.livy.groups</name>
<value>*</value>
<description>Allow the superuser livy to impersonate any members of the group group1 and group2</description>
</property>
<property>
<name>hadoop.proxyuser.livy.hosts</name>
<value>*</value>
<description>The superuser can connect only from host1 and host2 to impersonate a user</description>
</property>

如果不配置的话,会有
ERROR: org.apache.hadoop.security.authorize.AuthorizationException: User: livy is not allowed to impersonate xxx

该警告会影响任务的提交.

配置完成后,别忘了重启hdfs,livy,yarn等
