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.
Download the latest version of Apache Accumulo on the project website.
Getting Started
- Follow the quick start to install and run Accumulo
- Read the Accumulo documentation
- Run the Accumulo examples to learn how to write Accumulo clients
- View the Javadocs to learn the Accumulo API
More resources can be found on the project website.
Building
Accumulo uses Maven to compile, test, and package its source. The following
command will build the binary tar.gz from source. Add -DskipTests to build without
waiting for the tests to run.
mvn package
This command produces assemble/target/accumulo-<version>-bin.tar.gz
Contributing
Contributions are welcome to all Apache Accumulo repositories.

Export Control
<details> <summary>Click here to show/hide details</summary>This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See https://www.wassenaar.org/ for more information.
The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.
The following provides more details on the included cryptographic software:
Apache Accumulo uses the built-in java cryptography libraries in its RFile encryption implementation. See oracle's export-regulations doc for more details for on Java's cryptography features. Apache Accumulo also uses the bouncycastle library for some cryptographic technology as well. See the BouncyCastle site for more details on bouncycastle's cryptography features.
