Chen Liang commented on HDFS-13767: ----------------------------------- Thanks [~shv] and [~xkrogen] for the review and the comments! Post v002 patch. bq. It seems it would be better if there was a way for the AlignmentContext, a generic/pluggable component, to make the decision about how to handle the call I agree that this very HDFS-specific. An issue here is that while {{Server}} has AlignmentContext instance, AlignmentContext has both server side and client side implementation. And it can not be casted to GlobalStateIdContext because it is in a different package. So adding {{shouldDeferProcessing(Server.Call call)}}, or any method that checks whether to defer a call, means it will need to be added in client alignment context as well. Which makes no sense to me. The more I look at AlignmentContext, the more I think that it would be better if we separate server and client AlignmentContext in some way. Then we can introduce this defer check call to server side only. For now, I would prefer to leave it like this. bq. Why did you move setUpCluster() out of TestObserverNode#setUp() When it was in {{setUp()}}, it is still effectively being called for each test. Then, for the tests such as testMultiObserver, it gets called again in the test method with a different parameter. So for these tests, setUpCluster() was being called twice. This was a bug there. So I moved it to each test to fix this, since {{setUpCluster}} takes a parameter that can be different for each test. The other comments are addressed. I thought about using fast-tailing but was being lazy to figure out how to enable it. Thanks a lot for the sharing Erik :) ! it does make the tests a lot faster. > Add msync server implementation. > -------------------------------- > > Key: HDFS-13767 > URL: https://issues.apache.org/jira/browse/HDFS-13767 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: namenode > Reporter: Chen Liang > Assignee: Chen Liang > Priority: Major > Attachments: HDFS-13767-HDFS-12943.001.patch, > HDFS-13767-HDFS-12943.002.patch, HDFS-13767.WIP.001.patch, > HDFS-13767.WIP.002.patch, HDFS-13767.WIP.003.patch, HDFS-13767.WIP.004.patch > > > This is a followup on HDFS-13688, where msync API is introduced to > {{ClientProtocol}} but the server side implementation is missing.
