解决办法:
<!-- 在core-site.xml添加如下属性:-->
<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>localhost</value>
<description>The superuser can connect only from host1 and host2 to impersonate a user</description>
