=== Known issues
|
|
* When upgrading clusters from version 8.11.4 or earlier, if your cluster contains non-master-eligible nodes,
|
|
information about the new functionality of these upgraded nodes may not be registered properly with the master node.
|
|
This can lead to some new functionality added since 8.12.0 not being accessible on the upgraded cluster.
|
|
If your cluster is running on ECK 2.12.1 and above, this may cause problems with finalizing the upgrade.
|
|
To resolve this issue, perform a rolling restart on the non-master-eligible nodes once all Elasticsearch nodes
|
|
are upgraded. This issue is fixed in 8.15.0.
