(Significant improvement). > 2) Catch Java's ArrayOutOfBound Exception instead of checking array.length every time. (Significant improvement). > 3) Avoid setUnit validation (which is a HashSet lookup) when initialize default Memory/VCores ResourceInformation (Significant improvement). > 4) Avoid unnecessary loop array in Resource#toString/hashCode. (Some improvement). > 5) Removed readOnlyResources in BaseResource. (Minor improvement). > 6) Removed enum: MandatoryResources, use final integer instead.
