-------------------------------------
Summary: Extend Recon's health task to pick up container deletes
when container pipeline isn't available
Key: HDDS-8661
URL: https://issues.apache.org/jira/browse/HDDS-8661
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Christos Bisias
Assignee: Christos Bisias
Subtask of [HDDS-8538|https://issues.apache.org/jira/browse/HDDS-8538].
When a datanode dies and their containers go missing, calling
{color:#00875a}getContainerWithPipeline() {color:#172b4d}always results in an
exception while the pipeline isn't available. In case of dead datanodes, we
should be using {color:#00875a}getContainer() {color:#172b4d}instead which
checks only the SCM and if the container doesn't exist, throws an exception.
{color}{color}{color}{color}
When cleaning up missing containers, their datanodes aren't available and the
containers will be only deleted from the SCM. Recon's health task should pick
up the change and remove the container from its tables.
After trying to get a container along with a pipeline, also check just the SCM.
