Subject [ANNOUNCE] Apache HBase 2.1.0 is now available for download
Date Fri, 20 Jul 2018 02:00:19 GMT
The HBase team is happy to announce the immediate availability of HBase

Apache HBase™ is an open-source, distributed, versioned, non-relational
Apache HBase gives you low latency random access to billions of rows with
millions of columns atop non-specialized hardware. To learn more about
see https://hbase.apache.org/.

To download 2.1.0, visit our download page:


HBase 2.1.0 is the second minor release in the HBase 2.x line, which aims to
improve the stability and reliability of HBase. This release includes
240+ resolved issues since 2.0.0.

Notable new features include:
- Procedure v2 based replication peer modification. The advantage here is
that all the replication peer modification will be synchronous, which means
after the you come back from the call, you can make sure that all the
region servers have loaded the changes. Please see HBASE-19397 for more
- Serial Replication. Now in replication we can make sure the order of
pushing logs is same as the order of requests from client. Please see
HBASE-20046 and HBASE-9465 for more details.
