"query" node runs the query engine, which can execute the SQL queries;
"job" node will execute the cube build jobs, like run hive command, submit
MR, update cube status, etc.
"all" node will run both query engine and job engine.

You can submit a job on a "query" node, but the job's execution only
happens on the "job" or "all" node; they share the same meta store, "query"
node will write the job task to meta store, "job" node will read it and
then execute.

Hope this clarifies.
