------------------------------------------------------------------
The specific scenario is:
# Upgrade the server.
# *Do not* connect with any 4.15 client.
# Connecting a 4.14 client will cause this exception.
We *need* backwards compatibility tests! (But they are hard to write)
Edit: I have not been able to reproduce this!
I did this:
# Wipe HDFS and ZK
# Install HBase 1.4.10 and Phoenix 4.14.3.
# Create some tables, views, and indexes, and insert some data.
# Upgrade HBase and Phoenix to 1.5.0 (build from branch-1) and 4.15.0 (build
from 4.x-HBase-1.5).
# Restarted HBase.
# Connected with the 4.14.3 Phoenix client. Listed tables, selected data, with
index and without. No error.
[~vincentpoon] could post the precise steps you have taken?
