okay. So the queries tableau will run on the persisted data will be through SPARK SQL to improve performance and to take advantage of SPARK SQL.

Once in Hive, the data is accessible from the Tableau extract through Spark thrift server.

Denny ,I went through your blog, It was great help. I guess tableau beta connector also following the same procedure,you described in blog. I am building the Spark now. Basically what I don't get is, where to put my data so that tableau can extract. So Ismail,its just Spark SQL. No RDDs I think I am getting it now . We use spark for our big data processing and we want processed data (Rdd) into tableau. So we should put our data in hive metastore and tableau will extract it from there using this connector? Correct me if I am wrong. I guess I have to look at how thrift server works. ________________________________ From: Denny Lee <denny.g....@gmail.com<mailto:denny.g....@gmail.com>> Sent: Thursday, February 5, 2015 12:20 PM To: İsmail Keskin; Ashutosh Trivedi (MT2013030) Cc: user@spark.apache.org<mailto:user@spark.apache.org> Subject: Re: Tableau beta connector Some quick context behind how Tableau interacts with Spark / Hive can also be found at https://www.concur.com/blog/en-us/connect-tableau-to-sparksql - its for how to connect from Tableau to the thrift server before the official Tableau beta connector but should provide some of the additional context called out.

So, none of the RDD stuff applies, you just issue SQL queries from Tableau. The table metadata can come from Hive Metastore if you place your hive-site.xml to configuration directory of Spark.

I have few basics question: Will this connector be able to fetch the schemaRDDs into tableau. Will all the schemaRDDs be exposed to tableau? Basically I am not getting what tableau will fetch at data-source? Is it existing files in HDFS? RDDs or something else. Question may be naive but I did not get answer anywhere else. Would really appreciate if someone has already tried it, can help me with this.
