Alexander Kolbasov commented on HIVE-17942:
-------------------------------------------
[~janulatha] Thanks for the explanation. Can you provide some example showing
how HMSHandler configuration may be customized by a user?
Looking at the fix and at your comment - the most important part is that
HMSHandler's configuration may be different from general server configuration
and that's the one we should use during alterTable. The fact that it is
thread-local is interesting, but this is really an implementation detail of
HMSHandler.
It would be good to explain this in the story in the code comments.
Another question that I asked - since now the server configuration isn't used
by HiveALterHandle, should it still be Configurable? What is the value of
setConf()/getConf() calls in the new code?

> local. So, local changes are not visible.
