Sandeep Guggilam commented on PHOENIX-5636:
-------------------------------------------
[~abhishek.chouhan] and I had a look . Here are our thoughts:
# Extract out the main logic of checking the version compatibility into a
different function. Probably reuse the isCompatible function ?
# The function can check for all conditions populating a passed-in buffer with
the right error message
# The function can be unit tested as well for all scenarios ( right versions,
different minor versions, same major / different major versions etc )
# For major version check , it will be good to have client == server rather
than client >= server
> Improve the error message when client connects to server with higher major
> version

> When a 4.14 client connects to a 5.0 server, it errors out saying " Outdated
> jars. Newer Phoenix clients can't communicate with older Phoenix servers"
> It should probably error out with "Major version of client is less than that
> of the server"
