sodonnel opened a new pull request, #3512:
URL: https://github.com/apache/ozone/pull/3512
## What changes were proposed in this pull request?
This PR defines a ContainerHealthCheckInterface, with the following
definition:
```
ContainerHealthResult checkHealth(
ContainerInfo container, Set<ContainerReplica> replicas,
List<Pair<Integer, DatanodeDetails>> indexesPendingAdd,
List<Pair<Integer, DatanodeDetails>> indexesPendingDelete,
int remainingRedundancyForMaintenance);
}
```
And also an implementation for EC containers that can determine if an EC
container is over or under replicated. The interface will return a
ContainerHealthResult object that contains information about the health state.
Eg for under replicated, it will contain details about the remaining
redundancy, whether its due to decommission etc.
For now this class is standalone and unused. It will be integrated with
ReplicationManager soon via a new Jira.
