Going forward. So= in the future eg client=3D{ 4.14, 4.15, 4.16 } <-> server=3D{ 4.14, 4.15, 4= .16 }. This will allow for seamless rolling upgrades with rollback in all co= mmon scenarios.=20 Then, consider an exception for some combinations of 4.15 and 5.1? I have te= sted this and these versions are data compatible (create data with 1.5/4.14,= upgrade to 2.2/5.1) and at the HBase level the wire compatibility between 1= and 2 is good enough for normal client operations. If the version check did= n=E2=80=99t throw an exception I wonder if there would be any issue.=20 For your consideration.=20 > On Dec 21, 2019, at 2:40 AM, "larsh@apache.org" wrote: >=20 > =EF=BB=BF Yeah!
