> Key: SPARK-13065
> URL: https://issues.apache.org/jira/browse/SPARK-13065
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 1.6.0
> Environment: all
> Reporter: Andrew Davidson
> Priority: Minor
> Labels: twitter
> Original Estimate: 2h
> Remaining Estimate: 2h

> The twitter stream api is very powerful provides a lot of support for
> twitter.com side filtering of status objects. When ever possible we want to
> let twitter do as much work as possible for us.
> currently the spark twitter api only allows you to configure a small sub set
> of possible filters
> String{} filters = {"tag1", tag2"}
> JavaDStream<Status> tweets =TwitterUtils.createStream(ssc, twitterAuth,
> filters);
> The current implemenation does
> private[streaming]
> class TwitterReceiver(
> twitterAuth: Authorization,
> filters: Seq[String],
> storageLevel: StorageLevel
> ) extends Receiver[Status](storageLevel) with Logging {
> . . .
> val query = new FilterQuery
> if (filters.size > 0) {
> query.track(filters.mkString(","))
> newTwitterStream.filter(query)
> } else {
> newTwitterStream.sample()
> }
> ...
> rather than construct the FilterQuery object in TwitterReceiver.onStart(). we
> should be able to pass a FilterQueryObject
> looks like an easy fix. See source code links bellow
> kind regards
