Subject MapR Announces First High Availability Solution for Accumulo
Date Thu, 07 Jun 2012 14:09:36 GMT
This seems worthy of mentioning:

San Jose, CA – June 6, 2012 – MapR Technologies, Inc., the provider of
the open, enterprise-grade distribution for Apache Hadoop, today
announced that the integration and verification testing of Accumulo
with the MapR Distribution for Apache Hadoop M5 Edition has been
completed. MapR also announced the completion of rigorous performance
and scaling testing of Accumulo and Hadoop running on the Cisco
Unified Computing System (UCS).

Accumulo, originally developed by NSA and now an Apache project, is a
distributed key value store with fine grain security control based on
Google’s BigTable design. MapR provides Accumulo deployments with full
High Availability, no single points of failure, automated and stateful
failover, and rolling upgrades for high availability during routine
hardware and software maintenance.

“This is a major step forward for Accumulo,” said Leo Fox, CEO of
Tenacity Solutions, Incorporated. “MapR’s capabilities expand use
cases and areas where our Intelligence customer can benefit from
Accumulo without risking downtime or data loss.”

MapR also provides full data protection for Accumulo data with
Mirroring and Snapshots, features designed to efficiently maintain
data integrity and business continuity across clusters and sites.

MapR also verified Accumulo running on the latest Cisco UCS hardware
and verified significant performance advantages of Cisco UCS with the
EMC Greenplum MR Edition of Hadoop.
