Apache Hive Project Bylaws
| Table of Contents |
|---|
This document defines the bylaws under which the Apache Hive project operates. It defines the roles and responsibilities of the project, who may vote, how voting works, how conflicts are resolved, etc.

Commit access can be revoked by a unanimous vote of all the active PMC members (except the committer in question if they are also a PMC member).
Significant, pervasive features are often developed in a speculative branch of the repository. The PMC may grant commit rights on the branch to its consistent contributors, while the initiative is active. Branch committers are responsible for shepherding their feature into an active release and do not cast binding votes or vetoes in the project.
All Apache committers are required to have a signed Individual Contributor License Agreement (CLA) on file with the Apache Software Foundation. There is a Committer FAQ which provides more details on the requirements for Committers.

Vote | Meaning |
|---|---|
+1 | 'Yes,' 'Agree,' or 'the action should be performed.' In general, this vote also indicates a willingness on the behalf of the voter in 'making it happen'. |
+0 | This vote indicates a willingness for the action under consideration to go ahead. The voter, however will not be able to help. |
-0 | This vote indicates that the voter does not, in general, agree with the proposed action but is not concerned enough to prevent the action going ahead. |
-1 | This is a negative vote. On issues where consensus is required, this vote counts as a veto. All vetoes must contain an explanation of why the veto is appropriate. Vetoes with no explanation are void. It may also be appropriate for a -1 vote to include an alternative course of action. |
All participants in the Hive project are encouraged to show their agreement with or against a particular action by voting. For technical decisions, only the votes of active committers are binding. Non binding votes are still useful for those with binding votes to understand the perception of an action in the wider Hive community. For PMC decisions, only the votes of PMC members are binding.

Approval Type | Definition |
|---|---|
Consensus | For this to pass, all voters with binding votes must vote and there can be no binding vetoes (-1). Consensus votes are rarely required due to the impracticality of getting all eligible voters to cast a vote. |
Lazy Consensus | Lazy consensus requires 3 binding +1 votes and no binding vetoes. |
Lazy Majority | A lazy majority vote requires 3 binding +1 votes and more binding +1 votes that -1 votes. |
Lazy Approval | An action with lazy approval is implicitly allowed unless a -1 vote is received, at which time, depending on the type of action, either lazy majority or lazy consensus approval must be obtained. |
2/3 Majority | Some actions require a 2/3 majority of active committers or PMC members to pass. Such actions typically affect the foundation of the project (e.g. adopting a new codebase to replace an existing product). The higher threshold is designed to ensure such changes are strongly supported. To pass this vote requires at least 2/3 of binding vote holders to vote +1. |
Vetos
A valid, binding veto cannot be overruled. If a veto is cast, it must be accompanied by a valid reason explaining the reasons for the veto. The validity of a veto, if challenged, can be confirmed by anyone who has a binding vote. This does not necessarily signify agreement with the veto - merely that the veto is valid.

Actions | Description | Approval | Binding Votes | Minimum Length | Mailing List |
|---|---|---|---|---|---|
Code Change | A change made to a codebase of the project and committed by a committer. This includes source code, documentation, website content, etc. | one +1 from a committer who has not authored the patch followed by a Lazy approval (not counting the vote of the contributor), moving to lazy majority if a -1 is received | Active committers | 1 | JIRA (dev@hive.apache.org) |
Release Plan | Defines the timetable and actions for a release. The plan also nominates a Release Manager. | Lazy majority | Active committers | 3 | user@hive.apache.org |
Product Release | When a release of one of the project's products is ready, a vote is required to accept the release as an official release of the project. | Lazy Majority | Active PMC members | 3 | user@hive.apache.org |
Adoption of New Codebase | When the codebase for an existing, released product is to be replaced with an alternative codebase. If such a vote fails to gain approval, the existing code base will continue. This also covers the creation of new sub-projects and submodules within the project. | 2/3 majority | Active PMC members | 6 | dev@hive.apache.org |
New Committer | When a new committer is proposed for the project. | Lazy consensus | Active PMC members | 3 | private@hive.apache.org |
New PMC Member | When a committer is proposed for the PMC. | Lazy consensus | Active PMC members | 3 | private@hive.apache.org |
Committer Removal | When removal of commit privileges is sought. | Consensus | Active PMC members (excluding the committer in question if a member of the PMC). | 6 | private@hive.apache.org |
PMC Member Removal | When removal of a PMC member is sought. | Consensus | Active PMC members (excluding the member in question). | 6 | private@hive.apache.org |
Modifying Bylaws | Modifying this document. | 2/3 majority | Active PMC members | 6 | user@hive.apache.org |
| New Branch Committer | When a new branch committer is proposed for the project. | Lazy Consensus | Active PMC members | 3 | private@hive.apache.org |
| Removal of Branch Committer | When a branch committer is removed from the project. | Consensus | Active PMC members excluding the committer in question if they are PMC members too. | 6 | private@hive.apache.org |
