------------------------------------
Summary: In datanode once a container becomes unhealthy, datanode
restart fails.
Key: HDDS-1310
URL: https://issues.apache.org/jira/browse/HDDS-1310
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Datanode
Affects Versions: 0.3.0
Reporter: Sandeep Nemuri
When a container is marked as {{UNHEALTHY}} in a datanode, subsequent restart
of that datanode fails as it cannot generate ContainerReports anymore.
Unhealthy state of a container is not handled in ContainerReport generation
inside a datanode.
We get the below exception when a datanode tries to generate the
ContainerReport which contains unhealthy container(s)
