This release contains changes from 46 issues, comprised of bug-fixes, +performance improvements, build quality improvements, and more. See [Jira][JIRA_174] or the bottom of this page for a complete list. + +Below are resources for this release: + +* [User Manual][user_manual] - In-depth developer and administrator documentation. +* [Javadocs][javadoc] - Accumulo 1.7.4 API +* [Examples][examples] - Code with corresponding readme files that give step by step instructions for running example code. + +Accumulo follows [Semantic Versioning][semver] [guidelines][guidelines]. This release is a ?[patch version][patch_version]?, which means that +only backwards compatible bug fixes are introduced in this version. 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. Users of 1.6 or earlier that are seeking to upgrade to 1.7 should consider 1.7.4 as a starting point. + +## Major Changes + +### Fixed upgrade process to set version on all volumes + +During upgrades, only one volume in a multiple HDFS volume was updated with the correct version. This would cause all tablet servers +to complain and ultimately fail. [ACCUMULO-4686] fixes this by setting the version on all volumes. + +### Updated Accumulo to work with new releases of Guava + +In [ACCUMULO-4702], dependencies on Beta-annotated Guava classes and methods were removed. While Accumulo still +includes Guava 14 in its tarball, it will work with newer versions of Guava in client code. It has been tested to work +with Guava 23. + +### Updated RFile to prevent very large blocks + +RFiles now use windowed statistics ([ACCUMULO-4669]) to prevent very large blocks when key statistics are not uniform + +## Notable Changes + +* [ACCUMULO-4506] - Add a timeout to a replication RPC call +* [ACCUMULO-4619] - Add splits hung forever +* [ACCUMULO-4633] - Added check to prevent division by zero +* [ACCUMULO-4640] - Accumulo shell is expecting instance.volumens in client.conf instead of accumulo-site.xml +* [ACCUMULO-4657] -
