Revert "Ensure that HostRegexTableLoadBalancer propery changes are picked up" This reverts commit 2d126407ee960894611ee3044e4cf92036185048.
The Apache Accumulo™ sorted, distributed key/value store is a robust, scalable, high performance data storage and retrieval system. Apache Accumulo is based on Google's BigTable design and is built on top of Apache Hadoop, Zookeeper, and Thrift. Apache Accumulo features a few novel improvements on the BigTable design in the form of cell-based access control and a server-side programming mechanism that can modify key/value pairs at various points in the data management process. Other notable improvements and feature are outlined here.
To install and run an Accumulo binary distribution, follow the install instructions.
Accumulo has the following documentation which is viewable on the Accumulo website using the links below:
This documentation can also be found in Accumulo distributions:
Binary distribution - The User Manual can be found in the
docs directory. The Examples Readmes can be found in
docs/examples. While the source for the Examples is not included, the distribution has a jar with the compiled examples. This makes it easy to run them after following the install instructions.
Accumulo uses Maven to compile, test, and package its source. The following command will build the binary tar.gz from source. Note, these instructions will not work for the Accumulo binary distribution as it does not include source. If you just want to build without waiting for the tests to run, add
This command produces a file at the following location.
The public Accumulo API is composed of :
All public types in the following packages and their subpackages excluding those named impl, thrift, or crypto.
A type is a class, interface, or enum. Anything with public or protected acccess in an API type is in the API. This includes, but is not limited to: methods, members classes, interfaces, and enums. Package-private types in the above packages are not considered public API.
The following regex matches imports that are not Accumulo public API. This regex can be used with RegexpSingleline to automatically find suspicious imports in a project using Accumulo.
The Accumulo project maintains binary compatibility across this API within a major release, as defined in the Java Language Specification 3rd ed. Starting with Accumulo 1.6.2 and 1.7.0 all API changes will follow semver 2.0
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 http://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 crypographic technology as well. See the BouncyCastle FAQ for more details on bouncycastle’s cryptography features.
