The Apache Accumulo project is pleased to announce the release
of Apache Accumulo 1.9.0! This release contains many bug fixes,
performance improvements, security enhancements, build quality
improvements, and more.
This release is effectively a patch release for 1.8.x, and replaces the
1.8.x series. It was bumped to a minor release version, under
Semantic Versioning rules to accommodate a new API addition to in
order to deprecate the use of some third party library types leaking
into our public API.
Users of any previous 1.8.x release are strongly encouraged to
update as soon as possible to benefit from the improvements with
very little concern in change of underlying functionality. Users of
versions 1.7 and earlier are encouraged to develop a timely upgrade
plan to transition to 1.9.0, as their maintenance schedules allow.
Apache Accumulo® is a sorted, distributed key/value store that
provides robust, scalable data storage and retrieval. With
Apache Accumulo, users can store and manage large data sets
across a cluster. Accumulo uses Apache Hadoop's HDFS to store
its data and Apache ZooKeeper for consensus.
