Sergey Shelukhin updated HIVE-15688:
Description:
run.sh is very slow because it's 4 calls to slider, which means 4 JVMs, 4
connections to RM and other crap, for 2-5sec. of overhead per call, depending
on the machine/cluster.
What we need is a mode for llapservicedriver that would not generate run.sh,
but would rather run the cluster immediately by calling the corresponding 4
slider APIs. Should probably be the default, too. For compat with scripts we
might generate blank run.sh for now.
