  1. Do the following based on your configuration:
    Spark Target Configuration Description
    YARN using the Spark application The tdqg user must be able to impersonate other users and start the Spark application. Add the following entry in core-site.xml to enable impersonation:
    <property>
    	<name>hadoop.proxyuser.tdqg.hosts</name>
    	<value>*</value>
    </property>
    <property>
    	<name>hadoop.proxyuser.tdqg.groups</name>
    	<value>*</value>
    </property>
    This step is mandatory for non-Kerberos environments when using Spark. The core-site.xml file does not need to be updated for each new user.
    Standalone using the Spark Thrift Server The target user, specified by user mapping, must be the same user who started the Spark Thrift Server.
