A heads up for the Giraph user community that the Giraph PMC has been 'moved to the Attic'. This means that the Giraph developers (more formally its Project Management Committee) have voted to retire Giraph and move the responsibility for its oversight over to the Attic project.
Loosely speaking this means that the projects resources will be moved to a read-only state. You can read more about the Apache Attic and the process of moving to the Attic at https://attic.apache.org. You can follow this process in JIRA: https://issues.apache.org/jira/browse/ATTIC-217 Thanks, Hervé on behalf of Giraph + the Attic.
