Setting the layer's renderer outline to null in the ArcGIS JavaScript code makes the line causing the polygon split disappear. There is a small gap in the fill color of the polygon but it is less noticeable than the outline color. Use the following code to achieve the results: 

var renderer = {type: "simple",symbol: {type: "simple-fill",color: [ 255, 128, 0, 0.5 ],outline: null}};featureLayer = new FeatureLayer({url: //feature service url,renderer: renderer});
