Re: run spark apps in linux crontab

[Mich Talebzadeh]

you should source the environment file before or in the file. for example
this one is ksh type

0,5,10,15,20,25,30,35,40,45,50,55 * * * *
(/home/hduser/dba/bin/send_messages_to_Kafka.ksh >
/var/tmp/send_messages_to_Kafka.err 2>&1)

in that shell it sources the environment file

#
# Main Section
#
ENVFILE=/home/hduser/.kshrc
if [[ -f $ENVFILE ]]
then
        . $ENVFILE
else
        echo "Abort: $0 failed. No environment file ( $ENVFILE ) found"
        exit 1
fi

Or simply in your case say

0,5,10,15,20,25,30,35,40,45,50,55 * * * *
*(/home/hduser/.bashrc;*$SPARK_HOME/bin/spark-submit.......
> /var/tmp/somefile 2>&1)
