Introduction

Thanks for your interest in helping to vote on a release candidate!

Please review the Project Release Guide for details on the release process and procedures associated with voting.

Prerequisites

Download OpenPGP Keys for Signature Verification

wget https://dist.apache.org/repos/dist/release/nifi/KEYS

wget for Windows can be found here.

Import OpenPGP Keys

gpg --import KEYS

On Windows cmder includes gpg.

[Optional] Clear Local Maven Artifact Repository

rm -rf ~/.m2/repository/*

Verification Steps

Download Source Release Files

export VERSION=2.9.0

wget https://dist.apache.org/repos/dist/dev/nifi/nifi-$VERSION/nifi-$VERSION-source-release.zip
wget https://dist.apache.org/repos/dist/dev/nifi/nifi-$VERSION/nifi-$VERSION-source-release.zip.asc
wget https://dist.apache.org/repos/dist/dev/nifi/nifi-$VERSION/nifi-$VERSION-source-release.zip.sha512

Verify OpenPGP Signatures

gpg --verify -v nifi-$VERSION-source-release.zip.asc

Verify Hash Matches Source Release Files

Run the following commands on Linux or macOS:

shasum -a 512 nifi-$VERSION-source-release.zip

Run the following commands on Windows:

certutil -hashfile nifi-$VERSION-source-release.zip SHA512

Extract Source Release Files

unzip -DD nifi-$VERSION-source-release.zip

Verify Maven Build with Licensing and Style Checks

Use Maven Wrapper to build using the currently configured Maven version. The Maven Wrapper script is named mvnw for Linux and macOS, and mvnw.cmd for Windows.

cd nifi-$VERSION

Increasing the memory available to the JVM through Maven may be required on some systems, e.g. to build the NiFi UI:

export MAVEN_OPTS="-Xmx3000m"

On Linux or macOS

./mvnw -T 1C clean install -Pcontrib-check

On Windows

mvnw.cmd -T 1C clean install -Pcontrib-check

Verify Additional Source and Build Artifacts

• Verify the contents contain a good README, NOTICE, and LICENSE
• Verify the git commit ID is correct
• Verify the RC was branched off the correct git commit ID
• Look at the resulting convenience binaries as found in:
  • nifi-assembly/target
  • nifi-registry/nifi-registry-assembly/target
  • nifi-toolkit/nifi-toolkit-assembly/target
  • minifi/minifi-assembly/target
• Run the resulting convenience binaries
