Berkeley research project, designed to efficiently >> run machine learning algorithms on large datasets. Over time, it has >> evolved into a general computing engine as outlined above. Spark¹s >> developer community has also grown to include additional institutions, >> such as universities, research labs, and corporations. Funding has been >> provided by various institutions including the U.S. National Science >> Foundation, DARPA, and a number of industry sponsors. See: >> https://amplab.cs.berkeley.edu/sponsors/ for full details. >> >> === Rationale === >> As the number of contributors to Spark has grown, we have sought for a >> long-term home for the project, and we believe the Apache foundation >>would >> be a great fit. Spark is a natural fit for the Apache foundation: Spark >> already interoperates with several existing Apache projects (HDFS, >>HBase, >> Hive, Cassandra, Avro and Flume to name a few). The Spark team is >>familiar >> with the Apache process and and subscribes to the Apache mission - the >> team includes multiple Apache committers already. Finally, joining >>Apache >> will help coordinate the development effort of the growing number of >> organizations which contribute to Spark. >> >> == Initial Goals == >> The initial goals will most likely be to move the existing codebase to >> Apache and integrate with the Apache development process. Furthermore, >>we >> plan for incremental development, and releases along with the Apache >> guidelines. >> >> === Current Status === >> == Meritocracy == >> The Spark project already operates on meritocratic principles. Today, >> Spark has several developers and has accepted multiple major patches >>from >> outside of U.C. Berkeley. While this process has remained mostly >>informal >> (we do not have an official committer list), an implicit organization >> exists in which individuals who contribute major components act as >> maintainers for those modules. If accepted, the Spark project would >> include several of these participants as committers from the onset. We >> will work to identify all committers and PPMC members for the project >>and >> to operate under the ASF meritocratic principles. >> >> === Community === >> Acceptance into the Apache foundation would bolster the already strong >> user and developer community around Spark. That community includes >>dozens >> of contributors from several institutions, a meetup group with several >> hundred members, and an active mailing list composed of hundreds of >>users. >> Core Developers >> The core developers of our project are listed in our contributors and >> initial PPMC below. Though many exist at UC Berkeley, there is a >> representative cross sampling of other organizations including >>Quantifind, >> Microsoft, Yahoo!, ClearStory Data, Bizo, Intel, Tagged and Webtrends. >> >> >> === Alignment === >> Our proposed effort aligns with several ongoing BIGDATA and U.S. >>National >> priority funding interests including the NSF and its Expeditions >>program, >> and the DARPA XDATA project. Our industry partners and collaborators are >> well aligned with our code base. >> >> There are also a number of related Apache projects and dependencies, >>that >> will be mentioned in the Relationships with Other Apache products >>section. >> >> == Known Risks == >> >> === Orphaned Products === >> Given the current level of investment in Spark - the risk of the project >> being abandoned is minimal. There are several constituents who are >>highly >> incentivized to continue development. The U.C. Berkeley AMPLab relies on >> Spark as a platform for a large number of long-term research projects. >> Several companies have build verticalized products which are tightly >> dependent on Spark. Other companies have devoted significant internal >> infrastructure investment in Spark. >> >> === Inexperience with Open Source === >> Spark has existed as a healthy open source project for several years. >> During that time, Matei and others have curated an open-source community >> successfully, attracting developers from a diverse group of companies >> including Quantifind, Microsoft, Yahoo!, ClearStory Data, Bizo, Intel, >>and >> Webtrends. >> >> === Homogenous Developers === >> The initial list of committers includes developers from several >> institutions, including Quantifind, Microsoft, Yahoo!, ClearStory Data, >> Bizo, Intel, and Webtrends. >> >> === Reliance on Salaried Developers === >> Like most open source projects, Spark receives a substantial support >>from >> salaried developers. A large fraction of Spark development is supported >>by >> graduate students at U.C. Berkeley in the course of research degrees - >> this is more a ³volunteer² relationship, since in most cases students >> contribute vastly more than is necessary to immediately support >>research. >> In addition, those working from within corporations often devote ³after >> hours² or spare time in the project - and these come from several >> organizations. We will work to ensure that the ability for the project >>to >> continuously be stewarded and to proceed forward independent of salaried >> developers is continued. >> >> >> === Relationship with Other Apache Products === >> Spark inter-operates with several existing Apache products by supporting >> them as storage layers: Apache Cassandra, Apache HBase, and Apache >>Hadoop >> (HDFS). It also uses several Apache components internally including >>Apache >> Maven and several Apache Commons libraries. Finally, Shark (a higher >>layer >> framework built on Spark) inter-operates with Apache Hive. We will >>explore >> the relationship between Spark and Apache Gora, which also provides >> in-memory object storage (Champion Mattmann was the Champion for Apace >> Gora so we expect alignment and cross pollination between our efforts). >> >> Spark offers an alternative computation engine to Apache Hadoop >> (MapReduce). Unlike MapReduce, Spark is designed for lower-latency and >> interactive workloads. This makes the projects complimentary: many users >> run MapReduce and Spark side-by-side. >> >> === A Excessive Fascination with the Apache Brand === >> Spark is already a healthy and relatively well known open source >>project. >> This proposal is not for the purpose of generating publicity. Rather, >>the >> primary benefits to joining Apache are those outlined in the Rationale >> section. >> >> === Documentation === >> The reader will find these websites highly relevant: >> * Spark website: http://spark-project.org/ >> * Spark documentation: http://spark-project.org/documentation/ >> * Issue tracking: https://spark-project.atlassian.net/ >> * Codebase: https://github.com/mesos/spark >> * User group: https://groups.google.com/group/spark-users >> >> == Initial Source == >> The Spark codebase is currently hosted on Github: >> https://github.com/mesos/spark. This is the exact codebase that we would >> migrate to the Apache foundation. >> Source and Intellectual Property Submission Plan >> Currently, the Spark codebase is distributed under a BSD license. The >>vast >> majority of code has copyright held by the University of California. >>Upon >> entering Apache, Spark will migrate to an Apache License with all >> copyright assigned to the Apache Foundation. The University of >>California >> will transfer all copyright to the Apache Foundation. In certain cases >> where individuals hold copyright, we will have individuals sign over >> copyright to the Apache foundation as well. >> >> Going forward, all commits would assign copyright directly to the Apache >> foundation through our signed Individual Contributor License Agreements >> for all initial committers on the project. >> >> >> == External Dependencies == >> To the best of our knowledge, all dependencies of Spark are distributed >> under Apache compatible licenses. Upon acceptance to the incubator, we >> would begin a thorough analysis of all transitive dependencies to verify >> this fact and introduce license checking into the build and release >> process (for instance integrating Apache Rat). >> >> == Required Resources == >> === Mailing list === >> We will migrate the existing Spark mailing lists as follows: >> >> * spark-users@googlegroups --> us...@spark.incubator.apache.org >> * spark-developers@googlegroups --> d...@spark.incubator.apache.org >> * spark-commits are hosted on Github, so we would request >> comm...@spark.incubator.apache.org >> >> The latter is to be consistent with the new PIAO naming scheme for >> podlings. >> >> === Source control === >> The Spark team would like to use Git for source control, due to our >> current use of Git. >> We request a writeable Git repo for Spark, and mirroring to be set up to >> Github through INFRA. Champion Mattmann can assist with creating INFRA >> tickets for this. >> >> === Issue Tracking === >> Spark currently uses a hosted JIRA deployment for issue tracking.
