   1.use the newest Druid version( compiled from master branch, with sketches-core-0.13.1)
   2.use this python generate test data
   `import json
   f=open('test_theta_data','w')
   d={}
   for i in xrange(100000):
     #date_id,user_id
     d['date_id']='20190407'
     d['user_id']=i
     f.write('%s\n' % json.dumps(d))`
   3.use this Ingestion spec
   `{
     "dimensions": [
       "date_id"
     ], 
     "aggregations": [
       {
         "type": "thetaSketch", 
         "fieldName": "user_id", 
         "name": "count_distinct__user_id", 
       }
     ],
