Deploy Spark using CMDaemon
This example will deploy the spark master on the Head Node. All the workers deployed in the default category.
Install the package
Execute on the Head Node, below example is for RHEL8:
# yum clean all
# yum install cm-sparkNote: The spark package deploys everything to /cm/shared
Install the service files
Then execute the following (also on the Head Node):
# pushd /cm/shared/apps/spark/current/scripts
# systemctl link $PWD/spark-master.service
# systemctl enable spark-master
# systemctl start spark-master
# cp -prv $PWD/spark-worker@.service /usr/lib/systemd/system/
# cp -prv $PWD/spark-worker@.service /cm/images/default-image/usr/lib/systemd/system/
# systemctl enable spark-worker@master:7077.service
# systemctl start spark-worker@master:7077.service
# chroot /cm/images/default-image systemctl enable spark-worker@master:7077.service
# popdConfigure the Generic Roles for Master/Worker nodes
