Hama

What the board has decided about this committee or office, and the reports it filed, most recent first. Generated from the published minutes.

These categorised views are best effort. They are read from the published minutes by a program, and what it can attribute to a committee depends on how each resolution happens to be worded — so a page may be incomplete, and nothing here overrides the minutes themselves. The raw minutes are the source of truth.

Please note. The board approves the minutes of a meeting at the meeting after it, and they are published then - so the most recent meeting is not usually here. ASF Members can read the draft in the board's own repository until it is.

## Description:
 - Apache Hama is a framework for Big Data analytics based on the Bulk
   Synchronous Parallel paradigm

## Issues:
 - the PMC didn't manage to report in the last 3 board calls for reports.

## Activity:
 - the activity in the project is low. However new contributors have showed up
   in the mailing list and started creting Jira issues.

## Health report:
 - the community is not doing very good. Most of the committers / PMC members
   do not seem to have enough cycles to contribute to the project. We have
   raised awareness about the chance for Apache Hama to go Attic, calling out
   for new contributors. We have seen some positive responses from potential
   new contributors. We also have voted (submitted for this next board
   meeting) for a new PMC chair.

2012-03-21 — in the Incubator's report

Hama was accepted into Incubator on 20 May 2008. Hama is a distributed
computing framework based on BSP (Bulk Synchronous Parallel) computing
techniques for massive scientific computations.

Top 2 or 3 things to resolve prior to graduation

- Grow the community size.
- Making a ready-to-use release.

Issues for the Incubator PMC or ASF Board

- None.

Community development

- Increased contributions from new people interested in Hama.
  Apurv Verma and Suraj Menon did contributed great efforts to our project.
- Looking forward to participate in GSOC 2012 and invite new committers.

Project development

- Prepared Hama 0.4.0-incubating and benchmarked its performance
  (The concept is proofed).
- This release includes a lot of new features and improvements and
  is currently being voted.
  - Stabilized barrier synchronization.
  - Support Muli-tasks.
  - Input/Output Formatter like MapReduce.

2009-09-23 — in the Incubator's report

Hama has been incubating since 19 May, 2008. It is a parallel matrix
computational package based on Hadoop Map/Reduce.

Recent developments:

* We implemented EigenValue Decomposition, based on Map/Reduce computing
model
* We start considering about another computing model based Bulk Synchronous
  Parallel on Hadoop
* We start preparing a paper of this project

Required before graduation:

* More practical examples of matrix manipulation
* Increase community size and activity
* First Apache release

2008-08-20 — in the Incubator's report

Hama is a parallel matrix computational package based on Hadoop. The project
entered incubation on May 19th, 2008.

We are currently working to prepare the first release of Apache Hama in the
Apache Incubator. The first release Roadmap is planned. The number of dev
subscribers has increased. We should have a page about becoming
contributors. We will likely be adding a new project member soon. CCLA sent
for KRIBB and NHN's contribution.

2008-06-25 — in the Incubator's report

Incubating since: 19 May 2008

Mailing lists, subversion repository, and JIRA setup was completed.

Software Grant Agreement (Initial code owners are chanwit and me) was sended
for the intial donation of Hama code from the google project.

ICLAs were sent, But We are still waiting for the arrival of CCLAs.
