return ContainerClosingException/ContainerClosedException (CCE) to client
if the container is in Closing/Closed State
Shashikant Banerjee created HDDS-197:
----------------------------------------
Summary: DataNode should return Datanode to return ContainerClosingException/ContainerClosedException (CCE) to client if the container is in Closing/Closed State
Key: HDDS-197
URL: https://issues.apache.org/jira/browse/HDDS-197
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Client, Ozone Datanode
Reporter: Shashikant Banerjee
Assignee: Shashikant Banerjee
Fix For: 0.2.1
SCM queues the CloeContainer command to DataNode over herabeat response which is handled by the Ratis Server inside the Datanode. In Case, the container transitions to CLOSING/CLOSED state, while the ozone client is writing Data, It should throw ContainerClosingException/ContainerClosedExceptionContainerClosingException/ContainerClosedException accordingly. These exceptions will be handled by the client which will retry to get the last committed BlockInfo from Datanode and update the OzoneMaster.
