-------------------------------------
[~sushanth] Thanks for prompting me to take a closer look at the precedence! I
found an issue, here is the updated patch.
HIVE-7342.2.patch - With earlier patch hivemetastore-site.xml would take
precedence over hiveserver2-site.xml if embedded metastore is used with
hiveserver2, as metastore-site.xml was getting added later.
With this change HiveConf initialization itself would check if embedded
metastore is used and load the hivemetastore-site.xml. This way the order of
adding the resources to the Configuration always remains the same.
Patch also adds tests for both embedded and remote metastore mode.
The order of predendence (later one takes precedence) :
hive-site.xml -> hivemetastore-site.xml -> hiveserver2-site.xml ->
HiveConf.ConfVars set through system properties (same as ones set through
-hiveconf cmdline params)
> support hiveserver2,metastore specific config files

>
> 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.
