The Spark Execution Mechanism property is used by the QueryGrid Spark target connector to submit queries to Spark. Depending on this property setting, additional configuration is needed.
  1. Do one of the following based on your configuration:
    Configuration Description
    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.
    Spark Thrift Server No changes needed.
