Subject [jira] [Updated] (HIVE-7342) support hiveserver2,metastore specific config files
Date Tue, 15 Jul 2014 20:26:05 GMT


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

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

>         Attachments: HIVE-7342.1.patch, HIVE-7342.2.patch
> 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.
