apache zeppelin UPGRADE
Affected: >= 0.9.0 and < 0.12.1
Fixed in: 0.12.1
Safe to downgrade to: a release before 0.9.0
1. Check installed version
apt-cache policy zeppelin || rpm -q zeppelin || zeppelin --version
2. UPGRADE to 0.12.1 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade zeppelin
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade zeppelin
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 0.9.0 (Debian / Ubuntu)
apt-cache madison zeppelin
sudo apt install zeppelin=<VERSION_BEFORE_0.9.0>
sudo apt-mark hold zeppelin
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list zeppelin
sudo dnf downgrade zeppelin-<VERSION_BEFORE_0.9.0>
sudo dnf versionlock add zeppelin
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.
