----------------------------------------
Summary: Modify Close Container handling sequence on datanodes
Key: HDDS-709
URL: https://issues.apache.org/jira/browse/HDDS-709
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Datanode
Reporter: Shashikant Banerjee
Assignee: Shashikant Banerjee
With quasi closed container state for handling majority node failures, the
close container handling sequence in Datanodes need to change. Once the
datanodes receive a close container command from SCM, the open container
replicas individually be marked in the closing state. In a closing state, only
the transactions coming from the Ratis leader are allowed , all other write
transaction will fail. A close container transaction will be queued via Ratis
on the leader which will be replayed to the followers which makes it transition
to CLOSED/QUASI CLOSED state.
