Jaehwa Jung updated TAJO-433:
-----------------------------
Attachment: TAJO-433.patch
I'm glad to upload this patch. From now on, tajo can use HiveMetastore with
hive-site.xml. But verifying dependencies for hive was both tricky and
time-consuming job. I updated tajo as follows:
# HCatalogUtil: It made HiveMetaStoreClient using HiveConf. This update
affected HCatalogStore and TestHCatalogStore.
# pom.xml: some hive dependencies made trouble which load another hive
libraries. So, I checked all hive dependencies.
# tajo: Previous tajo added all jar files in hive library directory into class
path. But some jar files crashed tajo libraries. For example, tajo uses
protobuf version 2.5.0, but hive 0.12. uses protobuf version 2.4.1. So, After I
verified each jar file, I added it into class path.
# tajo-env.sh: I added HIVE_JDBC_DRIVER_DIR which specify hive jdbc driver jar
file path because HCatalogStore needed it.
You can verify this patch as follows:
{code:xml}
* for hive 0.11.0: mvn clean install -Phcatalog-0.11.0
* for hive 0.12.0: mvn clean install -Phcatalog-0.12.0

> Hi, guys~
> I wish to discuss about HCatalogStore.
> HiveMetaStore types consists of three types: embedded, local, remote.
> This type will set up at hive configuration file which named 'hive-site.xml'
> and HiveMetaStoreClient can use MetaStore by configuration file. So, if Tajo
> have only to add hive configuration file to classpath, Tajo can use
> HiveMetaStore with HiveMetaStoreClient.
> But current HCatalogStore set up configurations about HiveMetaStore as
> follows:
> - hive.metastore.uris
> - hive.metastore.kerberos.principal
> - hive.metastore.local
> - hive.metastore.sasl.enabled
> And Tajo doesn't need 'tajo.catalog.uri' property because 'hive-site.xml'
> already includes metastore host and port. So, it looks like unnecessary
> settings.
> What do you think about this suggestion? :)
