Why do we need to setup Spark Thrift Server?

smartninja723 — Tue, 17 May 2016 19:47:24 GMT

Hi Guys,

Sorry to sound dumb, but what is the use of Spark Thirft Server? We have Kerberized HDP 2.4.0 cluster. Recently installed Spark component on the HDP. Now when I am seeing the setup document, I see the option that talks about adding Spark Thrift Server component.

I googled a bit, it talks about JDBC along with thrift spark server. Not very clearly understood though.

I would like to understand more before making any changes to our Kerberized HDP 2.4 .

Many thanks.

Spark thrift server is pretty similar to hiveserver2 thrift, rather submitting the sql queries as hive mr job it will use spark SQL engine which underline uses full spark capabilities. As an use case tools like Tableau can easily connect to spark thrift server through ODBC driver just like hiveserver2 and access the hive or spark temp tables to run the sql queries on spark framework.

You only need to setup Spark Thrift Server if you need to provide access to SparkSQL via JDBC or ODBC. If you want to only use SparkSQL either programmatically (submit a spark app with Spark-submit) or with Spark-Shell, you don't need Spark Thrift Server.

Question, Spark Thrift Server should stay on Master or Worker nodes ?

with hiveserver2 you can also submit job on spark if spark is configured as execution engine in hive, right?
