[Apache Accumulo][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][dl].



## Getting Started



* Follow the [quick start] to install and run Accumulo

* Read the [Accumulo documentation][docs]

* Run the [Accumulo examples][examples] to learn how to write Accumulo clients

* View the [Javadocs][javadocs] to learn the [Accumulo API][api]



More resources can be found on the [project website][accumulo].



## 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--bin.tar.gz`

---



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  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][java-export]

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][bouncy-site] for

more details on bouncycastle's cryptography features.
