> Key: KYLIN-1826
> URL: https://issues.apache.org/jira/browse/KYLIN-1826
> Project: Kylin
> Issue Type: Improvement
> Components: Environment
> Affects Versions: v1.5.2
> Reporter: fengYu
> Assignee: fengYu
>
> Currently, kylin only support one hive which should run by 'hive' command,
> However, when source data located in more than one hive we should deploy more
> kylin instance and more than one metastore. which is difficult to manager and
> may cause some conflict.
> I has been working on it Recently, In our cluster, there are some hive
> client(different metastore) which based on different hadoop cluster, I add a
> new hive source type which called 'external hive' in kylin 1.5.x
> Thanks to kylin Plug-in architecture in 2.x, which make this work easiler.
> the main modification are:
> 1. add hive root directory in hive config file, external hive client exist in
> this directory. hive named by directory name.
> 2. add hive-site.xml file while loading hive tables.
> 3. store hive name into project, one project can only take one hive as source.
> 4. change and add some job to support job building.
> I will upload my patch if I finish all my tests.
