Shashikant Banerjee commented on HDDS-801:
------------------------------------------
Thanks [~nandakumar131] for working on this. Some comments
1.KeyValueHandler.java : 865 -> update the comment to be container getting
"quasi closed" rather than getting closed.
2.KeyValueHandler.java : 865 -> closeContainer is exposed to clients in
ContainerProtocolCalls.Java. With SCMCLi as well, the close container can be
invoked where a client can directly close (closeContainer in
ContainerOperationClient). In such cases, a container in may be in just open
state and hence the exception will be thrown:
{code:java}
// The container has to be in CLOSING state.
if (state != State.CLOSING) {
ContainerProtos.Result error = state == State.INVALID ?
INVALID_CONTAINER_STATE : CONTAINER_INTERNAL_ERROR;
throw new StorageContainerException("Cannot close container #" +
container.getContainerData().getContainerID() + " while in " +
state + " state.", error);
}{code}
Should we disallow/remove the closeContainer call exposed to clients/SCMCLI?
3. Any state change in ContainerState should triggerICR.In that case,
closeContainer/quasiCloseContainer call should call updateContainerState
internally to send ICR instead of executing individually.
