things stopping from running with readonly filesystem
tries to create
mkdir -p /var/lib/spark/worker mkdir -p /var/lib/spark/rdd mkdir -p /var/log/spark/worker mkdir -p /var/log/spark/master
registers volumes: "/var/lib/cassandra": {}, "/var/lib/dsefs": {}, "/var/lib/spark": {}, "/var/log/cassandra": {}, "/var/log/spark": {}
to make it run in readonly file system
./build.sh
#mount additional folders for write
#DSE_AUTO_CONF_OFF=all to avoid rewriting data in cassandra/conf file
./run.sh
