---------------------------------
Summary: SCM should not consider containers in CLOSING state to
come out of safemode
Key: HDDS-2198
URL: https://issues.apache.org/jira/browse/HDDS-2198
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: SCM
Reporter: Nanda kumar
Assignee: Nanda kumar
There are cases where SCM can be stuck in safemode for ever if it considers
containers in CLOSING state for coming out of safemode
* If there are 5 containers in OPEN state inside SCM
* Out of 5, 3 containers are created in datanodes by the client.
* 2 containers are yet to be created in datanodes
* Due to some pipeline issue, pipeline close action is sent.
* All 5 container's state are changed from OPEN to CLOSING in SCM.
* Eventually , 3 container's state moves from CLOSING to CLOSED in SCM as the
datanodes closes those containers.
* 2 of the containers are still in CLOSING state.
* SCM is restarted.
* SCM will never gets container reports for the containers which were in
CLOSING state as those containers were never created in datanodes.
* SCM will remain in safemode.
