Hi, all, there has been six months since we released 2.1.0. And there are 429 issues which fixed version is 2.2.0[1]. Our internal branch which based branch-2 run ITBLL successfully recently. branch-2 is stable now and it is time to release 2.2.0. I volunteered to be the release manager for the 2.2 release line. And plan to cut branch-2.2 from branch-2.
For 2.2.0, the biggest change is about AMV2[2]: HBASE-20881 is an incompatible change and different implemenation with branch-2.0 and branch-2.1. Need to add more document about how to rolling upgrade from 2.0.* or 2.1.* to 2.2.*. Meanwhile, need document about how rolling upgrade from 1.* to 2.2.*. Now HBCK2 tool support branch-2's region assignments, too. Another features will be included: 1. HBASE-20610 Procedure V2 - Distributed Log Splitting[3] 2. HBASE-21649 Complete Thrift2[4] 3. HBASE-16707 Improve throttling feature for production usage[5] 4. HBASE-20886 [Auth] Support keytab login in hbase client[6] 5. HBASE-20636 Introduce two bloom filter type : ROWPREFIX_FIXED_LENGTH and ROWPREFIX_DELIMITED[7] Open a issue HBASE-21747 to release 2.2.0[8]. Suggestions are welcomed. Thanks.
