Resend since the first one is rejected by the annou...@apache.org... The HBase team is happy to announce the immediate availability of HBase 2.1.0.
Apache HBaseâ„¢ is an open-source, distributed, versioned, non-relational database. Apache HBase gives you low latency random access to billions of rows with millions of columns atop non-specialized hardware. To learn more about HBase, see https://hbase.apache.org/. To download 2.1.0, visit our download page: http://hbase.apache.org/downloads.html 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 roughly 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 details. - 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. For other important changes: - The minimum hadoop version has been changed to 2.7.1. - We have successfully done a rolling upgrade from 1.4.3 to 2.1.0 which shows that rolling upgrade from 1.x to 2.x is possible. Notice that this is only an experimental feature, as there are likely uncovered corner cases in our limited test. See http://hbase.apache.org/book.html#upgrade2.0.rolling.upgrades for more details.
