Description

      int memory = Integer.parseInt(srv.get(ConfVars.LLAP_DAEMON_MEMORY_PER_INSTANCE_MB.varname));
      int vCores = Integer.parseInt(srv.get(ConfVars.LLAP_DAEMON_NUM_EXECUTORS.varname));
    

Needs to provide a useful error message when it fails because the config is bad. There may be other similar places.
