apache impala UPGRADE

Affected: >= 4.4.0 and <= 4.5.2

Fixed in: newer than 4.5.2

Safe to downgrade to: a release before 4.4.0

1. Check installed version

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

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade impala

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 4.4.0 (Debian / Ubuntu)

apt-cache madison impala sudo apt install impala=<VERSION_BEFORE_4.4.0> sudo apt-mark hold impala

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

dnf --showduplicates list impala sudo dnf downgrade impala-<VERSION_BEFORE_4.4.0> sudo dnf versionlock add impala

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.
