<h2>Apache Spark Community</h2>
<a name="have-questions"></a>
<h3>Have Questions?</h3>
<h4>StackOverflow</h4>
For usage questions and help (e.g. how to use this Spark API), it is recommended you use the
StackOverflow tag <a href="http://stackoverflow.com/questions/tagged/apache-spark">`apache-spark`</a>
as it is an active forum for Spark users' questions and answers.
Some quick tips when using StackOverflow:
- Prior to asking submitting questions, please:
- Search StackOverflow's
<a href="http://stackoverflow.com/questions/tagged/apache-spark">`apache-spark`</a> tag to see if
your question has already been answered
- Search the nabble archive for
<a href="http://apache-spark-user-list.1001560.n3.nabble.com/">users@spark.apache.org</a>
- Please follow the StackOverflow <a href="http://stackoverflow.com/help/how-to-ask">code of conduct</a>
- Always use the `apache-spark` tag when asking questions
- Please also use a secondary tag to specify components so subject matter experts can more easily find them.
Examples include: `pyspark`, `spark-dataframe`, `spark-streaming`, `spark-r`, `spark-mllib`,
`spark-ml`, `spark-graphx`, `spark-graphframes`, `spark-tensorframes`, etc.
- Please do not cross-post between StackOverflow and the mailing lists
- No jobs, sales, or solicitation is permitted on StackOverflow
<a name="mailing-lists"></a>
<h4>Mailing Lists</h4>
For broad, opinion based, ask for external resources, debug issues, bugs, contributing to the
project, and scenarios, it is recommended you use the user@spark.apache.org mailing list.
<ul>
<li>
<a href="http://apache-spark-user-list.1001560.n3.nabble.com">user@spark.apache.org</a> is for usage questions, help, and announcements.
<a href="mailto:user-subscribe@spark.apache.org?subject=(send%20this%20email%20to%20subscribe)">(subscribe)</a>
<a href="mailto:user-unsubscribe@spark.apache.org?subject=(send%20this%20email%20to%20unsubscribe)">(unsubscribe)</a>
<a href="http://apache-spark-user-list.1001560.n3.nabble.com">(archives)</a>
</li>
<li>
<a href="http://apache-spark-developers-list.1001551.n3.nabble.com">dev@spark.apache.org</a> is for people who want to contribute code to Spark.
<a href="mailto:dev-subscribe@spark.apache.org?subject=(send%20this%20email%20to%20subscribe)">(subscribe)</a>
<a href="mailto:dev-unsubscribe@spark.apache.org?subject=(send%20this%20email%20to%20unsubscribe)">(unsubscribe)</a>
<a href="http://apache-spark-developers-list.1001551.n3.nabble.com">(archives)</a>
</li>
</ul>
Some quick tips when using email:
- Prior to asking submitting questions, please:
- Search StackOverflow at <a href="http://stackoverflow.com/questions/tagged/apache-spark">`apache-spark`</a>
to see if your question has already been answered
- Search the nabble archive for
<a href="http://apache-spark-user-list.1001560.n3.nabble.com/">users@spark.apache.org</a>
- Tagging the subject line of your email will help you get a faster response, e.g.
`[Spark SQL]: Does Spark SQL support LEFT SEMI JOIN?`
- Tags may help identify a topic by:
- Component: Spark Core, Spark SQL, ML, MLlib, GraphFrames, GraphX, TensorFrames, etc
- Level: Beginner, Intermediate, Advanced
- Scenario: Debug, How-to
- For error logs or long code examples, please use <a href="https://gist.github.com/">GitHub gist</a>
and include only a few lines of the pertinent code / log within the email.
- No jobs, sales, or solicitation is permitted on the Apache Spark mailing lists.

<h3>Project History</h3>
<p>
Spark started as a research project at the <a href="https://amplab.cs.berkeley.edu">UC Berkeley AMPLab</a>
in 2009, and was open sourced in early 2010.
Many of the ideas behind the system are presented in various
<a href="{{site.baseurl}}/research.html">research papers</a>.
</p>
<p>
After being released, Spark grew a developer community on GitHub and moved to Apache in 2013.
A wide range of contributors now develop the project (over 400 developers from 100 companies).
