-----------------------------------

             Summary: NPE in LauncherMapper.printArgs()
                 Key: OOZIE-2748
                 URL: https://issues.apache.org/jira/browse/OOZIE-2748
             Project: Oozie
          Issue Type: Bug
          Components: core
    Affects Versions: 4.2.0
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko


If we define argument for the Spark action like this

{code}
        <spark xmlns="uri:oozie:spark-action:0.2">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <configuration>
                <property>
                    <name>oozie.use.system.libpath</name>
                    <value>true</value>
                </property>
                <property>
                    <name></name>
                    <value></value>
                </property>
            </configuration>
            <master>yarn-cluster</master>
            <mode>cluster</mode>
            <name>DataAnalyze</name>
              <class> Hive_Cis.DataAnalyze</class>
            
<jar>${nameNode}/Analytics/Spark_jars/Hive_CIS-1.0-SNAPSHOT-jar-with-dependencies.jar</jar>
              <spark-opts>--files 
${nameNode}/Analytics/Spark_jars/hive-site.xml</spark-opts>
              <arg></arg>
        </spark>
{code}

then we get a NullPointerException in LauncherMapper:

{code}
Failing Oozie Launcher, Main class [org.apache.oozie.action.hadoop.SparkMain], 
exception invoking main(), null
java.lang.NullPointerException
