Apache Accumulo® is a sorted, distributed key/value store that provides robust, scalable data storage and retrieval.

- Download - GitHub -
-

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. While many users interact directly with Accumulo, several open source projects use Accumulo as their underlying store.

-

To learn more about Accumulo, take the Accumulo tour, read the user manual and run the Accumulo example code. Feel free to contact us if you have any questions. +

Accumulo Summit is on October 15th!

Major Features

+Date:   05 Jul 2018
-
-
-

Server-side programming

-

Accumulo has a programing meachinism (called Iterators) that can modify key/value pairs at various points in the data management process.

-
-
-

Cell-based access control

-

Every Accumulo key/value pair has its own security label which limits query results based off user authorizations.

-
-
-
-
-

Designed to scale

-

Accumulo runs on a cluster using one or more HDFS instances. Nodes can be added or removed as the amount of data stored in Accumulo changes.

-
-
-

Stable

-

Accumulo has a stable client API that follows semantic versioning. Each Accumulo release goes through extensive testing.

-

A bug fix is defined as -an internal change that fixes incorrect behavior. Users of any previous 1.7.x release are strongly encouraged to update as soon as possible to benefit from the -bug fixes with very little concern in change of underlying functionality. As always, the Accumulo developers take API compatibility very seriously -and have invested much time to ensure that we meet the promises set forth to our users.

The real bug was in the -BoundedRangeFileInputStream.

It was updated at a configurable interval -initially as an optimization. Unfortunately it had the negative side effect of providing the assignment and balance operations with stale information. -This lead to a constant shuffling of tablets.

The recommended way is to stop Accumulo 1.6, perform the Accumulo upgrade to -1.7, and then start 1.7. Like previous versions, after 1.7.0 is started on a 1.6 instance, a one-time upgrade will -happen by the Master which will prevent a downgrade back to 1.6. Upgrades are still one way. Upgrades from versions -prior to 1.6 to 1.7 should follow the below path to 1.6 and then perform the upgrade to 1.7 – direct upgrades to 1.7 -for versions other than 1.6 are untested.</p> - -<p>After upgrading to 1.7.0, users will notice the addition of a <code class="highlighter-rouge">replication</code> table in the <code class="highlighter-rouge">accumulo</code> namespace. This -table is created and put offline to avoid any additional maintenance if the data-center replication feature is not -in use.</p> - -<p>Existing configuration files from 1.6 should be compared against the examples provided in 1.7. The 1.6 configuration -files should all function with 1.7 code, but you will likely want to include a new file (hadoop-metrics2-accumulo.properties) -to enable the new metrics subsystem. Read the section on Hadoop Metrics2 in the Administration chapter of the Accumulo User Manual.</p> - -<p>For each of the other new features, new configuration properties exist to support the feature. Refer to the added -sections in the User Manual for the feature for information on how to properly configure and use the new functionality.</p> - -<h2 id="testing">Testing</h2> - -<p>Each unit and functional test only runs on a single node, while the RandomWalk and Continuous Ingest tests run on any number of nodes. Agitation refers to randomly restarting Accumulo processes and Hadoop Datanode processes, and, in HDFS High-Availability instances, forcing NameNode failover.</p> - -<table id="release_notes_testing" class="table"> - <thead> - <tr> - <th>OS/Environment</th> - <th>Hadoop</th> - <th>Nodes</th> - <th>ZooKeeper</th> - <th>HDFS HA</th> - <th>Tests</th> - </tr> - </thead> - <tbody> - <tr> - <td>CentOS 7, openJDK 1.8 from CentOS yum repo, EC2; 1 leader m3.xlarge, 8 workers d2.xlarge</td> - <td>2.7.3</td> - <td>9</td> - <td>3.4.9</td> - <td>No</td> - <td>24 HR Continuous Ingest without Agitation</td> - </tr> - <tr> - <td>CentOS 7, openJDK 1.8 from CentOS yum repo, EC2; 1 leader m3.xlarge, 8 workers d2.xlarge</td> - <td>2.7.3</td> - <td>9</td> - <td>3.4.9</td> - <td>No</td> - <td>24 HR Continuous Ingest Agitation</td> - </tr> - </tbody> -</table> - - - Thu, 06 Apr 2017 00:00:00 -0400 - https://accumulo.apache.org/release/accumulo-1.7.3/ - https://accumulo.apache.org/release/accumulo-1.7.3/ - - - release - - - diff --git a/index.html b/index.html index 3e38f63..ee9ed47 100644 --- a/index.html +++ b/index.html @@ -189,6 +189,13 @@
