Thus when we copy manifest in ExportSnapshot, we can copy reference files concurrently and use the paths it returns to help setOwner and setPermission. +The size of thread pool is determined by the configuration snapshot.export.copy.references.threads, and its default value is the number of runtime available processors. + + +--- + +* [HBASE-18116](https://issues.apache.org/jira/browse/HBASE-18116) | *Major* | **Replication source in-memory accounting should not include bulk transfer hfiles** + +Before this change we would incorrectly include the size of enqueued store files for bulk replication in the calculation for determining whether or not to rate limit the transfer of WAL edits. Because bulk replication uses a separate and asynchronous mechanism for file transfer this could incorrectly limit the batch sizes for WAL replication if bulk replication in progress, with negative impact on latency and throughput. + + +--- + +* [HBASE-20592](https://issues.apache.org/jira/browse/HBASE-20592) | *Minor* | **Create a tool to verify tables do not have prefix tree encoding** + +PreUpgradeValidator tool with DataBlockEncoding validator was added to verify cluster is upgradable to HBase 2. + + +--- + +* [HBASE-20501](https://issues.apache.org/jira/browse/HBASE-20501) | *Blocker* | **Change the Hadoop minimum version to 2.7.1** + + +HBase is no longer able to maintain compatibility with Apache Hadoop versions that are no longer receiving updates. This release raises the minimum supported version to Hadoop 2.7.1. Downstream users are strongly advised to upgrade to the latest Hadoop 2.7 maintenance release. + +Downstream users of earlier HBase versions are similarly advised to upgrade to Hadoop 2.7.1+. When doing so, it is especially important to follow the guidance from [the HBase Reference Guide's Hadoop section](http://hbase.apache.org/book.html#hadoop) on replacing the Hadoop artifacts bundled with HBase. + + +--- + +* [HBASE-20601](https://issues.apache.org/jira/browse/HBASE-20601) | *Minor* | **Add multiPut support and other miscellaneous to PE** + +1. Add multiPut support +Set --multiPut=number to enable batchput(meanwhile, --autoflush need be set to false) + +2. Add Connection Count support +Added a new parameter connCount to PE. set --connCount=2 means all threads will share 2 connections. +oneCon option and connCount option shouldn't be set at the same time. + +3.

When created via the `HBaseTestingUtility`, ports for Master and RegionServer services and UIs will be set to random ports to allow for multiple parallel uses on a single machine. Normally when running a Standalone HBase Deployment (as described in the HBase Reference Guide) the ports will be picked according to the same defaults used in a full cluster set up. If you wish to instead use the random port assignment set `hbase.localcluster.assign.random.ports` to true. + + +--- + +* [HBASE-20004](https://issues.apache.org/jira/browse/HBASE-20004) | *Minor* | **Client is not able to execute REST queries in a secure cluster** + +Added 'hbase.rest.http.allow.options.method' configuration property to allow user to decide whether Rest Server HTTP should allow OPTIONS method or not. By default it is enabled in HBase 2.1.0+ versions and in other versions it is disabled. +Similarly 'hbase.thrift.http.allow.options.method' is added HBase 1.5, 2.1.0 and 3.0.0 versions. It is disabled by default. + + +--- + +* [HBASE-20327](https://issues.apache.org/jira/browse/HBASE-20327) | *Minor* | **When qualifier is not specified, append and incr operation do not work (shell)** + +This change will enable users to perform append and increment operation with null qualifier via hbase-shell. + + +--- + +* [HBASE-18842](https://issues.apache.org/jira/browse/HBASE-18842) | *Minor* | **The hbase shell clone\_snaphost command returns bad error message** + + + +When attempting to clone a snapshot but using a namespace that does not exist, the HBase shell will now correctly report the exception as caused by the passed namespace. Previously, the shell would report that the problem was an unknown namespace but it would claim the user provided table name was not found as a namespace. Both before and after this change the shell properly used the passed namespace to attempt to handle the request. + + +--- + +* [HBASE-20406](https://issues.apache.org/jira/browse/HBASE-20406) | *Major* | **HBase Thrift HTTP - Shouldn't handle TRACE/OPTIONS methods** + + +When configured to do thrift-over-http, the HBase Thrift API Server no longer accepts the HTTP methods TRACE nor OPTIONS. + + +--- + +* [HBASE-20046](https://issues.apache.org/jira/browse/HBASE-20046) | *Major* | **Reconsider the implementation for serial replication** + +Now in replication we can make sure the order of pushing logs is same as the order of requests from client.

We also support Durability.FSYNC\_WAL, which instead triggers HDFS hsync() to flush \_and\_ fsync edits. This change introduces the new configuration setting "hbase.wal.hsync", defaulting to FALSE, that if set to TRUE changes the default durability setting for the synchronous WAL to FSYNC\_WAL. + + +--- + +* [HBASE-19389](https://issues.apache.org/jira/browse/HBASE-19389) | *Critical* | **Limit concurrency of put with dense (hundreds) columns to prevent write handler exhausted** + +After HBASE-19389 we introduced a RegionServer self-protection mechanism to prevent write handler getting exhausted by high concurrency put with dense columns, mainly through two new properties: hbase.region.store.parallel.put.limit.min.column.count to decide what kind of put (with how many columns within a single column family) to limit (100 by default) and hbase.region.store.parallel.put.limit to limit the concurrency (10 by default).

Call pre CP hook, if an exception is thrown then give up +2. Check whether the operation is valid, if not then give up +3. Update peer storage. Notice that if we have entered this stage, then we can not rollback any more. +4. Schedule sub procedures to refresh the peer config on every RS. +5. Do post cleanup if any. +6. Call post CP hook.
