-Release 0.16.0
-
- 2008/02/04 HBase is now a subproject of Hadoop. The first HBase release as
- a subproject will be release 0.1.0 which will be equivalent to
- the version of HBase included in Hadoop 0.16.0. In order to
- accomplish this, the HBase portion of HBASE-288 (formerly
- HADOOP-1398) has been backed out. Once 0.1.0 is frozen (depending
- mostly on changes to infrastructure due to becoming a sub project
- instead of a contrib project), this patch will re-appear on HBase
- trunk.

+# HBASE 2.2.0 Release Notes
+
+These release notes cover new developer and user-facing incompatibilities, important issues, features, and major improvements.
+
+
+---
+
+* [HBASE-15728](https://issues.apache.org/jira/browse/HBASE-15728) | *Major* | **Add remaining per-table region / store / flush / compaction related metrics**
+
+Adds below flush, split, and compaction metrics
+
+ + // split related metrics
+ + private MutableFastCounter splitRequest;
+ + private MutableFastCounter splitSuccess;
+ + private MetricHistogram splitTimeHisto;
+ +
+ + // flush related metrics

+ + private MutableFastCounter majorCompactedOutputBytes;
+
+
+---
+
+* [HBASE-20886](https://issues.apache.org/jira/browse/HBASE-20886) | *Critical* | **[Auth] Support keytab login in hbase client**
+
+From 2.2.0, hbase supports client login via keytab. To use this feature, client should specify \`hbase.client.keytab.file\` and \`hbase.client.keytab.principal\` in hbase-site.xml, then the connection will contain the needed credentials which be renewed periodically to communicate with kerberized hbase cluster.
+
+
+---
+
+* [HBASE-21410](https://issues.apache.org/jira/browse/HBASE-21410) | *Major* | **A helper page that help find all problematic regions and procedures**
+
+After HBASE-21410, we add a helper page to Master UI. This helper page is mainly to help HBase operator quickly found all regions and pids that are get stuck.
+There are 2 entries to get in this page.
+One is showing in the Regions in Transition section, it made "num region(s) in transition" a link that you can click and check all regions in transition and their related procedure IDs.
+The other one is showing in the table details section, it made the number of CLOSING or OPENING regions a link, which you can click and check regions and related procedure IDs of CLOSING or OPENING regions of a certain table.
+In this helper page, not only you can see all regions and related procedures, there are 2 buttons at the top which will show these regions or procedure IDs in text format. This is mainly aim to help operator to easily copy and paste all problematic procedure IDs and encoded region names to HBCK2's command line, by which we HBase operator can bypass these procedures or assign these regions.
+
+
+---
+
+* [HBASE-21588](https://issues.apache.org/jira/browse/HBASE-21588) | *Major* | **Procedure v2 wal splitting implementation**
+
+After HBASE-21588, we introduce a new way to do WAL splitting coordination by procedure framework. This can simplify the process of WAL splitting and no need to connect zookeeper any more.
+During ServerCrashProcedure, it will create a SplitWALProcedure for each WAL that need to split. Then each SplitWALProcedure will spawn a SplitWALRemoteProcedure to send the request to regionserver.
+At the RegionServer side, whole process is handled by SplitWALCallable. It split the WAL and return the result to master.
+According to my test, this patch has a better performance as the number of WALs that need to split increase. And it can relieve the pressure on zookeeper.
+
+
+---
+
+* [HBASE-20734](https://issues.apache.org/jira/browse/HBASE-20734) | *Major* | **Colocate recovered edits directory with hbase.wal.dir**

+Previously the recovered.edits directory was under the root directory. This JIRA moves the recovered.edits directory to be under the hbase.wal.dir if set. It also adds a check for any recovered.edits found under the root directory for backwards compatibility. This gives improvements when a faster media(like SSD) or more local FileSystem is used for the hbase.wal.dir than the root dir.

+* [HBASE-20401](https://issues.apache.org/jira/browse/HBASE-20401) | *Minor* | **Make \`MAX\_WAIT\` and \`waitIfNotFinished\` in CleanerContext configurable**
+
+When oldwals (and hfile) cleaner cleans stale wals (and hfiles), it will periodically check and wait the clean results from filesystem, the total wait time will be no more than a max time.
+
+The periodically wait and check configurations are hbase.oldwals.cleaner.thread.check.interval.msec (default is 500 ms) and hbase.regionserver.hfilecleaner.thread.check.interval.msec (default is 1000 ms).
+
+Meanwhile, The max time configurations are hbase.oldwals.cleaner.thread.timeout.msec and hbase.regionserver.hfilecleaner.thread.timeout.msec, they are set to 60 seconds by default.
+
+All support dynamic configuration.
+
+e.g. in the oldwals cleaning scenario, one may consider tuning hbase.oldwals.cleaner.thread.timeout.msec and hbase.oldwals.cleaner.thread.check.interval.msec
+
+1. While deleting a oldwal never complete (strange but possible), then delete file task needs to wait for a max of 60 seconds. Here, 60 seconds might be too long, or the opposite way is to increase more than 60 seconds in the use cases of slow file delete.
+2. The check and wait of a file delete is set to default in the period of 500 milliseconds, one might want to tune this checking period to a short interval to check more frequently or to a longer interval to avoid checking too often to manage their delete file task checking period (the longer interval may be use to avoid checking too fast while using a high latency storage).

+* [HBASE-20724](https://issues.apache.org/jira/browse/HBASE-20724) | *Critical* | **Sometimes some compacted storefiles are still opened after region failover**
+
+Problem: This is an old problem since HBASE-2231. The compaction event marker was only writed to WAL. But after flush, the WAL may be archived, which means an useful compaction event marker be deleted, too. So the compacted store files cannot be archived when region open and replay WAL.
+
+Solution: After this jira, the compaction event tracker will be writed to HFile. When region open and load store files, read the compaction evnet tracker from HFile and archive the compacted store files which still exist.

+* [HBASE-21820](https://issues.apache.org/jira/browse/HBASE-21820) | *Major* | **Implement CLUSTER quota scope**
+
+HBase contains two quota scopes: MACHINE and CLUSTER. Before this patch, set quota operations did not expose scope option to client api and use MACHINE as default, CLUSTER scope can not be set and used.
+Shell commands are as follows:
+set\_quota, TYPE =\> THROTTLE, TABLE =\> 't1', LIMIT =\> '10req/sec'
+
+This issue implements CLUSTER scope in a simple way: For user, namespace, user over namespace quota, use [ClusterLimit / RSNum] as machine limit. For table and user over table quota, use [ClusterLimit / TotalTableRegionNum \* MachineTableRegionNum] as machine limit.
+After this patch, user can set CLUSTER scope quota, but MACHINE is still default if user ignore scope.
+Shell commands are as follows:
+set\_quota, TYPE =\> THROTTLE, TABLE =\> 't1', LIMIT =\> '10req/sec'

+
+Support enable or disable exceed throttle quota. Exceed throttle quota means, user can over consume user/namespace/table quota if region server has additional available quota because other users don't consume at the same time.
+Use the following shell commands to enable/disable exceed throttle quota: enable\_exceed\_throttle\_quota
+disable\_exceed\_throttle\_quota
+There are two limits when enable exceed throttle quota:
+1. Must set at least one read and one write region server throttle quota;
+2. All region server throttle quotas must be in seconds time unit. Because once previous requests exceed their quota and consume region server quota, quota in other time units may be refilled in a long time, this may affect later requests.

+* [HBASE-21734](https://issues.apache.org/jira/browse/HBASE-21734) | *Major* | **Some optimization in FilterListWithOR**
+
+After HBASE-21620, the filterListWithOR has been a bit slow because we need to merge each sub-filter's RC , while before HBASE-21620, we will skip many RC merging, but the logic was wrong. So here we choose another way to optimaze the performance: removing the KeyValueUtil#toNewKeyCell.
+Anoop Sam John suggested that the KeyValueUtil#toNewKeyCell can save some GC before because if we copy key part of cell into a single byte[], then the block the cell refering won't be refered by the filter list any more, the upper layer can GC the data block quickly. while after HBASE-21620, we will update the prevCellList for every encountered cell now, so the lifecycle of cell in prevCellList for FilterList will be quite shorter. so just use the cell ref for saving cpu.
+BTW, we removed all the arrays streams usage in filter list, because it's also quite time-consuming in our test.

So in this issue, we remove all ConcurrentSkipListMap#size in memstore by counting the cellsCount in MemstoreSizeing. As the issue described, the p999 latency spike was mitigated.

+
+In HBASE-21657, I simplified the path of estimatedSerialiedSize() & estimatedSerialiedSizeOfCell() by moving the general getSerializedSize()
+and heapSize() from ExtendedCell to Cell interface. The patch also included some other improvments:
+
+1. For 99% of case, our cells has no tags, so let the HFileScannerImpl just return the NoTagsByteBufferKeyValue if no tags, which means we can save
+ lots of cpu time when sending no tags cell to rpc because can just return the length instead of getting the serialize size by caculating offset/length
+ of each fields(row/cf/cq..)
+2. Move the subclass's getSerializedSize implementation from ExtendedCell to their own class, which mean we did not need to call ExtendedCell's
+ getSerialiedSize() firstly, then forward to subclass's getSerializedSize(withTags).
+3. Give a estimated result arraylist size for avoiding the frequent list extension when in a big scan, now we estimate the array size as min(scan.rows, 512).
+ it's also help a lot.
+
+We gain almost ~40% throughput improvement in 100% scan case for branch-2 (cacheHitRatio~100%)[1], it's a good thing. While it's a incompatible change in
+some case, such as if the upstream user implemented their own Cells, although it's rare but can happen, then their compile will be error.

+* User initiates Scan operations set to use the default reading type that read more than 4 * the block size of column families involved in the scan (e.g. by default 4*64KiB)
+* Compactions run
+
+### Root cause
+
+When there are long running scans the Region Server process attempts to optimize access by using a different API geared towards sequential access. Due to an error in HBASE-20704 for HBase 2.0+ the Region Server fails to release related resources when those scans finish. That same optimization path is always used for the HBase internal file compaction process.
+
+### Workaround
+
+Impact for this error can be minimized by setting the config value “hbase.storescanner.pread.max.bytes” to MAX_INT to avoid the optimization for default user scans. Clients should also be checked to ensure they do not pass the STREAM read type to the Scan API. This will have a severe impact on performance for long scans.
+
+Compactions always use this sequential optimized reading mechanism so downstream users will need to periodically restart Region Server roles after compactions have happened.

+3. The reason why we can not set the locked field directly to true by calling doAcquireLock is that, during initialization, most procedures need to wait until master is initialized.
