Ning Zhang commented on HIVE-675:
---------------------------------

Hi Carl, 

Branch 0.6 currently is broken when running a unit test. The error is as follows:


compile-test:
    [javac] /data/users/nzhang/reviews/0.6/branch-0.6/build-common.xml:307: warning: 'includeantruntime'
was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
    [javac] Compiling 4 source files to /data/users/nzhang/reviews/0.6/branch-0.6/build/metastore/test/classes
    [javac] /data/users/nzhang/reviews/0.6/branch-0.6/metastore/src/test/org/apache/hadoop/hive/metastore/TestHiveMetaStoreRemote.java:76:

    [javac]     TestHiveMetaStore.partitionTester(client, hiveConf, true);
    [javac]                      ^
    [javac] 1 error


It seems the last patch that touches TestHiveMetaStore and TestHiveMetaStoreRemote is this
patch. Can you take a look?

> Currently all Hive tables reside in single namespace (default). Hive should support multiple
namespaces (databases or schemas) such that users can create tables in their specific namespaces.
These name spaces can have different warehouse directories (with a default naming scheme)
and possibly different properties.
> There is already some support for this in metastore but Hive query parser should have
this feature as well.
