Hi Yang & all,
I checked hive config by "hive -e set" in the server which kylin deployed,
seems nothing wrong.
Then I tried to run sample.sh in kylin/bin , it created tables: "kylin_cal_dt"
"kylin_category_groupings" "kylin_sales" successfully and I can find these in
metastore DB (mysql) .
Need I do some config in kylin.properties to make it load hive table metadata
by hive remote model? I guess some property make it use hive default Derby .
Below is my hive-site.xml:
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/metastore?createDatabaseIfNotExist=true</value>
<description>metadata is stored in a MySQL server</description>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
<description>MySQL JDBC driver class</description>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>hive</value>
<description>user name for connecting to mysql server</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>password</value>
<description>password for connecting to mysql server</description>
</property>
<property>
<name>hive.metastore.uris</name>
<value>thrift://10.224.243.127:9083</value>
</property>
<property>
<name>hive.metastore.schema.verification</name>
<value>false</value>
</property>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/user/hive/warehouse</value>
</property>
<!--<property>
<name>hive.server.thrift.port</name>
<value>10000</value>
</property> -->
</configuration>

????: Re: how to load table from hive
What matters is the hive-site.xml Kylin picks up. Kylin detects hive config by
command `hive -e set`. You can try hive command line on the node where Kylin is
deployed and make sure it connects to the desired metastore.
Try diagnose `bin/find-hive-dependency.sh` if you still got problem.

Hi Kylin developers,
I'm a newbie for Kylin. Glad to see the excellent OLAP tool. As a Chinese acmen
, I like the name.
After I download and run it , I can access the website(http://IP:7070/kylin)
and create project successfully . However, when I try to load Hive table,
"NoSuchObjectException" alert (Oops...) !
From kylin.log in tomcat , I found some sensitive tracks:
2015-12-24 15:01:16,613 INFO [http-bio-7070-exec-6] metastore.ObjectStore:

2015-12-24 15:01:24,350 INFO [http-bio-7070-exec-6]
metastore.MetaStoreDirectSql: Using direct SQL, underlying DB is DERBY
I'm not sure these ignored property is OK or not.
I config Hive as remote mode(use mysql to store metadata, config thrift uris)
but kylin try to access DERBY which I do not use !
Could you tell me how to config it ?
