Ambari-Server error on restart: Unable to find stack definitions under stackRoot

ymoiseev — Tue, 21 Apr 2026 12:28:21 GMT

Hi,

After restarting ambari server, it failed to launch and we started to have following error:

Ambari database consistency check started...
No errors were found.
ERROR: Exiting with exit code 1.
REASON: Database check failed to complete. Please check /var/log/ambari-server/ambari-server.log and /var/log/ambari-server/ambari-server-check-database.log for more information.

In logs, we can find this:

Error injecting constructor, org.apache.ambari.server.AmbariException: Unable to find stack definitions under stackRoot = /var/lib/ambari-server/resources/stacks

Has anyone encounter this error before? What might be the reason why it happened and what are the possible solutions?

We're using HDF 2.0 on RHEL7
