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
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

---
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.
