Fix the checkstyle warning. The javadoc and the asf license issues seem
unrelated, the failed tests also seem unrelated. All passed locally except for
the two consistently failing tests {{TestUnbuffer}} and {{TestBalancerRPCDelay}}

[jira] [Updated] (HDFS-12000) Ozone: Container : Add key versioning support-1
[ https://issues.apache.org/jira/browse/HDFS-12000?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Chen Liang updated HDFS-12000: -- Attachment: HDFS-12000-HDFS-7240.009.patch Thanks [~xyao] for the review and the comments! Update v009 patch. bq. I think it will work when we only have one version, i.e., latest version. Correct me if I'm wrong, say we have K1 (B1V1, B2V2), with getBlocksLatestVersionOnly, are we going to get B2V2 instead of (B1V1, B2V2)? Exactly right, for now, getBlocksLatestVersionOnly() will only return the blocks from the most recent version, B2V2 only in your case. In the next few steps, my plan for multiple versions is to augment APIs that specifies which historical version to read. For example, an API that specifies read(K1, version=1), then it will ignore B2V2 but only look at B1V1. bq. Line 173: NIT: more comment does not valid any more Fixed Additionally, I have one major right now, that I'm looking for advices, is that I believe the dominating majority of read will be reading only the most recent version, in this case always iterating all the blocks including old version can become inefficient. Any comments on this are appreciated. bq. Line 268: should this openVersion as part of the request so that the client can request open certain version? It is ok to assume open the latest version for now. Maybe add a TODO for next JIRA on this feature. Yes, like mentioned above, in follow JIRA, there will be API that allows request specific version, old or recent. It will likely be using this field. Added a TODO note to the comments and follow up in next JIRAs. bq. Line 111: Is there a reason why the KsyKeyLocationInfo#Builder does not support setCreateVersion? Do we expect it to be set directly on the KsyKeyLocationInfo afterwards? I found that when a block is allocated, it gets allocated first then version is set based on whether it's appending to current version, or added as a new version. I think conceptually, a block itself does not have the notion of version. So, yes, I leave the block builder not setting version but the caller should set it after creating the block. bq. Line 22: NIT: unused imports Fixed bq. Line 58: if the version starts from 0, the special handling for currentVersion==-1 is not needed. Can you confirm? You are right. Thanks for the catch. Fixed bq. Line 30: can the open version be committed without close, something like hsync to populate the write without closing file. We don't need the open version, as it is only used when opening a key to disambiguate preallocated blocks. More specifically, when a key is opened, depending on whether size is specified, KeyManager *may or may not* have pre-allocated some blocks and returned in open session. If pre-allocation does happen, the returned latest version is the version to write. But if pre-allocation did not happen, the returned latest version is actually an old, already committed version that should not be written. The only purpose of this open version field is to distinguish these two cases. This value gets checked one time on client when loading pre-allocated blocks, then never used. So I think we don't need to commit it. > Ozone: Container : Add key versioning support-1 > --- > > Key: HDFS-12000 > URL: https://issues.apache.org/jira/browse/HDFS-12000 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ozone >Affects Versions: HDFS-7240 >Reporter: Anu Engineer >Assignee: Chen Liang > Labels: OzonePostMerge > Attachments: HDFS-12000-HDFS-7240.001.patch, > HDFS-12000-HDFS-7240.002.patch, HDFS-12000-HDFS-7240.003.patch, > HDFS-12000-HDFS-7240.004.patch, HDFS-12000-HDFS-7240.005.patch, > HDFS-12000-HDFS-7240.007.patch, HDFS-12000-HDFS-7240.008.patch, > HDFS-12000-HDFS-7240.009.patch, OzoneVersion.001.pdf > > > The rest interface of ozone supports versioning of keys.

Specifically, this patch adds versioning to blocks and persistent the information of the older versions to meta store.

[ https://issues.apache.org/jira/browse/HDFS-12000?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Chen Liang updated HDFS-12000: -- Attachment: HDFS-12000-HDFS-7240.004.patch Thanks [~xyao] for the comments! Addressed all your comments in v004 patch except the following: bq. Line 281: Please file followup JIRAs for TODO bq. Line 81: NIT: getLatestVersionList -> getLatestLocations, can we modify this function to take version as parameter so that this can be reused later when versions other than latest are fully supported. Will definitely do. Since it will actually involve some more code of retrieving the version, new APIs of requesting/returning specific version etc, I was planning for having a separate JIRA about getting specific version of block. there will be a couple of more JIRAs for versioning to work fully, reading a specific version will be one of the next JIRAs for sure. bq. Since we only update the latestVersion at commit time, there could be multiple clients that allocate blocks before the first commit is done. Once the first commit is done, all the allocate will be invalid to commit due to the logic between line 109-115. This is exactly what I was trying to do in this part. When multiple clients try to write the data, only one will succeed, the others will get exception, and maybe retry later. This works just same purpose as a write lock, such that when multiple writes are racing, we will never end up having a version that is an uncertain mix of multiple different writes. In addition, since delete key work is in-progress, I will need to look closer to see if there is anything conflicting between delete key and this versioning code. Submitting v004 patch anyway for now mainly for early review purpose. > Ozone: Container : Add key versioning support-1 > --- > > Key: HDFS-12000 > URL: https://issues.apache.org/jira/browse/HDFS-12000 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ozone >Affects Versions: HDFS-7240 >Reporter: Anu Engineer >Assignee: Chen Liang > Attachments: HDFS-12000-HDFS-7240.001.patch, > HDFS-12000-HDFS-7240.002.patch, HDFS-12000-HDFS-7240.003.patch, > HDFS-12000-HDFS-7240.004.patch, OzoneVersion.001.pdf > > > The rest interface of ozone supports versioning of keys.
