>> spark-submit (
>> http://spark.apache.org/docs/latest/submitting-applications.html); this

>> ODBC/JDBC API (
>> http://spark.apache.org/docs/latest/sql-programming-guide.html#distributed-sql-engine)
>> which enables applications to issue SQL queries against SparkSQL.

>> == Core Developers ==
>> The core developers of the project are currently all from IBM, from the

>> Technology Center.

>> Apache, as the home of Apache Spark, is the most natural home for the

>> == Known Risks ==

>> === Orphaned products ===
>> We believe the Torii project has a low-risk of abandonment due to interest

>> 
>> === Inexperience with Open Source ===
>> The Torii project has been running as an open-source project (albeit with
>> only IBM committers) for the past several months. The project has an active
>> issue tracker and due to the interest indicated by the nature and volume of
>> requests and comments, the team has publicly stated it is beginning to
>> build a process so they can accept third-party contributions to the project.
>> 
>> === Relationships with Other Apache Products ===
>> The Torii has a clear affinity with the Apache Spark project because it is
>> designed to  provide capabilities for interactive applications and data
>> science tools not provided by Spark itself. The Torii can be a back-end for
>> the Zeppelin project currently incubating at Apache. There is interest from

>> === Homogeneous Developers ===
>> The current group of developers working on Torii are all from IBM although

>> of the GitHub community who are not from IBM and who have been active in
>> the Torii community in GutHub.
>> 
>> === Reliance on Salaried Developers ===
>> The initial committers are full-time employees at IBM although not all
>> work on the project full-time.
>> 
>> === Excessive Fascination with the Apache Brand ===
>> We believe the Torii benefits Apache Spark application developers, and we

>> Spark project, and yes, gaining more visibility for the Torii as a solution.
