> HiveMetaStoreAuthorizer creating new HiveConf per thread increases overhead
> ---------------------------------------------------------------------------
>
> Key: HIVE-29330
> URL: https://issues.apache.org/jira/browse/HIVE-29330
> Project: Hive
> Issue Type: Improvement
> Reporter: Zhihua Deng
> Assignee: Zhihua Deng
> Priority: Major
>
> HiveMetaStoreAuthorizer can act as the pre event listener inside the HMS, or
> as the metadata filter hook on the client. If it's insides the HMS, getConf()
> should have loaded all properties in hive-site.xml, otherwise it contains the
> information to talk with the HMS at least, as the call is from client as a
> filter hook.
> We don't need to create a new HiveConf per thread, it's wasteful and might
> spend dozens of milliseconds to load the properties, log the warn message
> "HiveConf of name xx does not exist" continuously if the property is only
> specified in MetastoreConf.
