apache nifi UPGRADE

Affected: >= 1.2.0 and < 2.10.0

Fixed in: 2.10.0

Safe to downgrade to: a release before 1.2.0

1. Check installed version

apt-cache policy nifi || rpm -q nifi || nifi --version

2. UPGRADE to 2.10.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade nifi

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade nifi

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.2.0 (Debian / Ubuntu)

apt-cache madison nifi sudo apt install nifi=<VERSION_BEFORE_1.2.0> sudo apt-mark hold nifi

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list nifi sudo dnf downgrade nifi-<VERSION_BEFORE_1.2.0> sudo dnf versionlock add nifi

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
