Subject [jira] [Updated] (TAJO-336) Separate catalog stores into separate modules

JaeHwa Jung updated TAJO-336:
-----------------------------

    Attachment: TAJO-336_2.patch

Thanks guys!

I moved '/tajo-hive' to '/tajo-catalog/tajo-catalog-drivers/tajo-hcatalog'. If catalog store
modules located on root directory, it may make many directories and it may look like inefficient.
And if we want to add more catalog store, we just need to add catalog store module on 'tajo-catalog-drivers'.

And I separated catalog drives module from main module. If we execute 'mvn clean install'
or 'mvn pacakage -Pdist', tajo doesn't build hcatalog module. If we want to build hcatalog
module, we must specify hcatalog version and hadoop version as follows:
{code:xml}
mvn clean package -Pdist -Phcatalog-0.12.0 -Phadoop20 (hive-0.12.0 and hadoop-1.x.x)
mvn clean package -Pdist -Phcatalog-0.12.0 -Phadoop26 (hive-0.12.0 and hadoop-2.0.6-alpha)
{code}

Finally, If users want to use HCatalogStore, users must set HIVE_HOME at tajo-env.sh. If users
set HIVE_HOME, tajo shell add hcatalog dependencies to classpath.

P.S I'll write a wiki document which describe how to integrate with hive this week. :)

> Catalog stores, such as HCatalogStore, involves dependencies to other systems. Their
dependencies may be conflict from Tajo's dependencies because the dependent library versions
can be varied in many cases.
> As to this problem, separating catalog stores from catalog-server module would be a good
solution.
