> Cloudant has a plan called "Lite" supporting only five requests per second. So you end up with the following exception:
> org.apache.spark.SparkException: Job aborted due to stage failure: Task 4 in stage 0.0 failed 10 times, most recent failure: Lost task 4.9 in stage 0.0 (TID 42, yp-spark-dal09-env5-0040): java.lang.RuntimeException: Database harlemshake2 request error: {"error":"too_many_requests","reason":"You've exceeded your current limit of 5 requests per second for query class. Please try later.","class":"query","rate":5}
> 	at org.apache.bahir.cloudant.common.JsonStoreDataAccess.getQueryResult(JsonStoreDataAccess.scala:158)
> 	at org.apache.bahir.cloudant.common.JsonStoreDataAccess.getIterator(JsonStoreDataAccess.scala:72)
> Suggestion: Change JsonStoreDataAccess.scala in a way that when a 403 HTTP status code is returned the response is parsed in order to obtain the rate limit and then throttle the query down to that limit. In addition issue a WARNING in the log
