----------------------------------
Summary: OM follower should trigger failover if it is installing
snapshot
Key: HDDS-14593
URL: https://issues.apache.org/jira/browse/HDDS-14593
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ivan Andika
Assignee: Ivan Andika
When OM follower is installing snapshot, its appliedIndex will not advance
until the snapshot is installed (i.e. OM DB is fully downloaded to the OM
follower). This can cause all linearizable follower read on this node to
timeout due to the client timeout (default is 3s).
Instead of waiting until the client timeout, OM follower can check whether it
is currently installing snapshot and trigger failover immediately if it does.
