Naveen Gangam commented on HIVE-13688:
--------------------------------------
Thanks [~xuefuz] good to hear from you.
Good point. However, looking at the patch from
https://issues.apache.org/jira/secure/attachment/12742071/HIVE-6791.5-beeline-cli.patch
it appears the substitution for the shell commands seems to occurring on the
client side (beeline) in Commands.substituteVariables() which is using the
variables returned by "set" statement (from getConfInternal()) which should
return variables set for that session (specific HS2 instance).
Is my understanding incorrect? Thanks
