About testing, see my earlier comment. To do any real tests for this, one needs to do 'sudo' and then run tests. I have not found an easy way to do that in Hive. HCatalog has test infrastructure which makes this kind of thing possible, where I am adding these tests. See, HCATALOG-181 Also, I have manually verified all four combinations of new/old client and new/old server and results were of my satisfaction. trunk/conf/hive-default.xml.template <https://reviews.apache.org/r/2975/#comment9018> I will update the text. But, I think splitting it in two properties will be more confusing then useful. If ever some one uses them and both client and server somehow uses same hive-site.xml, then having one property make sure its either turned on or off for both client and server. trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java <https://reviews.apache.org/r/2975/#comment9019> will fix trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java <https://reviews.apache.org/r/2975/#comment9020> will fix trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java <https://reviews.apache.org/r/2975/#comment9024> Will add. trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStoreClient.java <https://reviews.apache.org/r/2975/#comment9021> In my opinion thats a right behavior because you dont want existing application to break when server is upgraded and is running with setugi on.
