-----------------------------
Summary: kylin support more than one hive based on different
hadoop claster
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.
