Sergey Shelukhin commented on HIVE-15688:
-----------------------------------------
run.sh is still generated, and could be used to restart the cluster. I can
change the default behavior though. Having an extra JVM still has a lot of
overhead given how big Hive classpath, configs, etc. is, and most of the time
people want to start the cluster immediately after generating the package.

> 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.
