LLAP failed to start on a host with only 1 cpu
LLAP failed to start on a host with only 1 cpu. The number of thread was
calculating by dividing the number of cpus with 2. This resulted zero if the
cpu count was 1 and caused an IllegalArgumentException upon startup. Fixed this
by adding Math.max(1, cpus/2).
