Thejas M Nair updated HIVE-7342:
--------------------------------
Release Note:
Adds support for server specific config files.
HiveMetastore server reads hive-site.xml as well as hivemetastore-site.xml
configuration files that are available in the $HIVE_CONF_DIR or in the
classpath. If metastore is being used in embedded mode (ie hive.metastore.uris
is not set or empty) in hive commandline or hiveserver2, the
hivemetastore-site.xml gets loaded by the parent process as well.
The value of hive.metastore.uris is examined to determine this, and the value
should be set appropriately in hive-site.xml .
HiveServer2 reads hive-site.xml as well as hiveserver2-site.xml that are
available in the $HIVE_CONF_DIR or in the classpath.
If hiveserver2 is using metastore in embedded mode, hivemetastore-site.xml also
is loaded.
The order of precedence of the config files is as follows (later one has higher
precedence) -
hive-site.xml -> hivemetastore-site.xml -> hiveserver2-site.xml -> '-hiveconf'
commandline parameters
> support hiveserver2,metastore specific config files

> 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,
> hivemetastore-site.xml) that override the entries in hive-site.xml will make
> the configuration much more easy to manage.
