Cannot call methods on a stopped SparkContext

[wukaishanda08]

I build train deploy the engine successfully. But when i excute the query commad, an exception occured.
The query command is

curl -k -H "Content-Type: application/json" -d '{ 'intlPlan': True, 'voiceMailPlan': True,'numVmailMsg': 41, 'totalDayMins': 173.1,'totalDayCalls': 85, 'totalDayCharge': 29.43,'totalEveMins': 203.9, 'totalEveCalls': 107,'totalEveCharge': 17.33, 'totalNightMins': 122.2, 'totalNightCalls': 78, 'totalNightCharge': 14.02,'totalIntlMins': 10.0,'totalIntlCalls': 15, 'totalIntlCharge': 3.94, 'customerServiceCalls': 0}' https://localhost:8150/queries.json

and the exception log is

Is there anybody knows how to solve this? Thanks a lot!
