Hadoop Streaming Job not working in OOzie

Question

I am trying to write a simple map only hadoop streaming job reading data from hdfs and pushing it to vertica.

I have written a shell script as below

./vsql -c "copy $TABLE from stdin delimiter E'\t' direct null '\\N';" -U $DBUSER -w $DBPWD -h $DBHOST -p $DBPORT

I have created oozie workflow as :

 <action name="loadToVertica">
        <map-reduce>
                            <job-tracker>${jobTracker}</job-tracker>
                            <name-node>${nameNode}</name-node>
                            <prepare>
                                    <delete path="${nameNode}/user/$USER/output/${exportDataDate}"/>
                            </prepare>
                            <streaming>
                                    <mapper>shell export.sh</mapper>
                            </streaming>
                            <configuration>

                                            <value>${nameNode}/user/$USER/output/${exportDataDate}</value>

            <ok to="end"/>
           <error to="end"/>
        </action>

When i run this the status of job is Failed/Killed without any error message.

Answer 1

Adding -e in after #!/bin/sh helped me to trace what the actual error is.

After adding -e option in the script there was an error code in the logs.

After this the first line would look like :

#!/bin/sh -e
