Sushanth Sowmyan commented on HIVE-7342:
----------------------------------------
I'm +1 on the .2.patch.
Having said that, I also wanted to bring up one more possible corner case that
seems to exist, one that I do not think needs solving(at least not right away -
might be worth opening a follow up to declare if a confvar can be overridden by
a conf or not), but one that exists anyway.
Consider the case of a hive client, that loads a hive-site.xml, and finds that
the metastore uris parameter is blank. Thus, it expects that it is a local
metastore operation, and thus, loads hivemetastore-site.xml. In this config,
however, say the uris parameter is not blank. Then, at connect time, that hive
client will act upon the uris value, which tells it that it is not a local
metastore, and connects out to the referred url. However, this hive client has
now loaded the metastore conf for other parameters, while still being a remote
client that talks to a metastore.

> Project: Hive
> Issue Type: Bug
> Components: Configuration, HiveServer2, Metastore
> Reporter: Thejas M Nair

>
> There is currently a single configuration file for all components in hive.
> ie, components such as hive cli, hiveserver2 and metastore all read from the
> same hive-site.xml.
> It will be useful to have a server specific hive-site.xml, so that you can
> have some different configuration value set for a server. For example, you
> might want to enabled authorization checks for hiveserver2, while disabling
> the checks for hive cli. The workaround today is to add any component
> specific configuration as a commandline (-hiveconf) argument.
> Using server specific config files (eg hiveserver2-site.xml,
> metastore-site.xml) that override the entries in hive-site.xml will make the
> configuration much more easy to manage.
