var  jobData = JSON.parse(data);

Am getting

                                                                              ^
SyntaxError: Unexpected end of input
    at Object.parse (native)

code 

var options = {
                    host: '172.16.2.120',
                    path: '/getModes?mode=' + jobLists,
                    port: '8080',
                    method: 'GET'
                };

                var reqOs = http.request(options, function (resOs) {
                    resOs.on('data', function (data) {              
                   var jobData = JSON.parse(data);              
                    });
                    resOs.on('end', function () {           

                    });
                });
                reqOs.on('error', function (e) {
                    console.log('problem with request: ' + e.message);
                });
                reqOs.end('');

You need to accumulate the chunks of data passed to the data event handler, and process them when the HTTP request has ended:

var reqOs = http.request(options, function (resOs) {
  var chunks = [];
  resOs.on('data', function (chunk) {
    chunks.push(chunk);
  });
  resOs.on('end', function () {
    var json    = Buffer.concat(chunks);
    var jobData = JSON.parse(json);
    ...
  });
});

The reason for this is that the data event can be triggered in the middle of reading a response.

It looks like the JSON string your server is responding is not valid:

1afcec877d925d110","date":"Mon Jan 06 2014 09:33:13 GMT+0530 (IST)","id":"51",
                                                                             ^

If the string ends like that, it's not valid JSON. Check the JSON string your server is returning and try to make it valid.
