The HBase team is happy to announce the immediate availability of Apache HBase 2.0.0-beta-1!
Apache HBase 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/. Download through an ASF mirror: https://www.apache.org/dyn/closer.lua/hbase/ (It may take a while to show up on a particular mirror site) hbase-2.0.0-beta-1 is our first beta release. It includes all that was in previous alphas (new assignment manager, offheap read/write path, in-memory compactions, etc.) only now the APIs and feature-set are sealed as we run up to our hbase-2.0.0 release. hbase-2.0.0-beta-1 is a not-for-production preview of hbase-2.0.0. It is meant for devs and downstreamers to test drive and flag us if we messed up on anything ahead of our rolling GAs. We are particular interested in hearing from Coprocessor developers. The list of features addressed in 2.0.0 so far can be found here [3]. There are thousands. The list of ~2k+ fixes in 2.0.0 exclusively can be found here [4]. I've updated our overview doc. on the state of 2.0.0 [6]. We'll do one more beta before we put up our first 2.0.0 Release Candidate by the end of February, 2.0.0-beta-2. Its focus will be making it so users can do a rolling upgrade onto hbase-2.x from hbase-1.x (and any bug fixes found running beta-1). Here is the list of what we have targeted so far for beta-2 [5]. Check it out. One known issue is that the User API has not been properly filtered so it shows more than just InterfaceAudience Public content (HBASE-19663, to be fixed by beta-2). Please take this beta for a spin. Let us know if you find any issue so we can fix it before we GA.
