Xiaoyu Yao commented on HDDS-347:
---------------------------------
Thanks [~GeLiXin] for working on this. The patch looks good to me. I think the
key to address the issue is wait for containerData.isClosed instead of
!isOpened with the introduction of the closing state.
Can you clarify if the sleep is still necessary?

> This issue was finded in the automatic JenKins unit test of HDDS-265.
> The container life cycle state is : Open -> Closing -> closed, this test
> submit the container close command and wait for container state change to
> *not equal to open*, actually even when the state condition(not equal to
> open) is satisfied, the container may still in process of closing, so the LOG
> which will printf after the container closed can't be find sometimes and the
> test fails.
> {code:java|title=KeyValueContainer.java|borderStyle=solid}
> try {
> writeLock();
> containerData.closeContainer();
> File containerFile = getContainerFile();
> // update the new container data to .container File
> updateContainerFile(containerFile);
> } catch (StorageContainerException ex) {
> {code}
> Looking at the code above, the container state changes from CLOSING to CLOSED
> in the first step, the remaining *updateContainerFile* may take hundreds of
> milliseconds, so even we modify the test logic to wait for the *CLOSED* state
> will not guarantee the test success, too.
> These are two way to fix this:
> 1, Remove one of the double check which depends on the LOG.
> 2, If we have to preserve the double check, we should wait for the *CLOSED*
> state and sleep for a while to wait for the LOG appears.
> patch 000 is based on the second way.
