             Summary: Provide a new service interface prompt function framework to resolved the defect of the current service interface, increase the flexibility of the function, improve user ease of use
                 Key: RANGER-1860
                 URL: https://issues.apache.org/jira/browse/RANGER-1860
             Project: Ranger
          Issue Type: Bug
          Components: admin
            Reporter: Qiang Zhang
            Assignee: Qiang Zhang


The ranger used the hard-coded way to achieve the service interface prompt function, the result is that the codes have worse maintainability.
{code}
if(!isPolicyForm) {
	if(v.name == 'yarn.url'){
		formObj.type = 'TextFiledWithIcon';
		formObj.errorMsg = localization.tt("hintMsg.yarnRestUrl");
	}else if(v.name == 'sqoop.url'){
		formObj.type = 'TextFiledWithIcon';
		formObj.errorMsg = localization.tt("hintMsg.sqoopRestUrl");
	}else if(v.name == 'jdbc.url'){
		formObj.type = 'TextFiledWithIcon';
		formObj.errorMsg = localization.tt("hintMsg.hiveJDBCUrl");
	}else if(v.name == 'fs.default.name'){
		formObj.type = 'TextFiledWithIcon';
		formObj.errorMsg = localization.tt("hintMsg.hdfsNameNodeUrl");
	}else{
		formObj.type = 'Text';
	}
	break;
}
{code}
Using the new issue we can directly modify the configuration file to meet the requirements of the new prompt function. Such as we can modify the following configuration to meet following requirements: 
the configuration in the ranger-servicedef-yarn.json is as follows：
{code}
"configs": 
[
	{
		"itemId": 3,
		"name": "yarn.url",
		"type": "string",
		"mandatory": true,
		"defaultValue": "",
		"validationRegEx":"",
		"validationMessage": "",
		"uiHint":"{\"TextFiledWithIcon\":true, \"info\": \"1.For one url, eg.<br>'http or https://&lt;ipaddr&gt;:8088'<br>2.For multiple urls (use , or ; delimiter), eg.<br>'http://&lt;ipaddr1&gt;:8088,http://&lt;ipaddr2&gt;:8088'\"}",
		"label": "YARN REST URL"
	}
]
{code}
requirements: 
adding text field with an icon( i.e information) on service form page,we should add unified configuration management functions in the service definition.
