Currently, Kylin on Parquet already supports debuging source code with local
csv files, but it's a little bit complex. The steps are as follows:
* edit the properties of
$KYLIN_SOURCE_DIR/examples/test_case_data/sandbox/kylin.properties to local
```log
kylin.metadata.url=$LOCAL_META_DIR
kylin.env.zookeeper-is-local=true
kylin.env.hdfs-working-dir=file:///path/to/local/dir
kylin.engine.spark-conf.spark.master=local
kylin.engine.spark-conf.spark.eventLog.dir=/path/to/local/dir
```
* debug org.apache.kylin.rest.DebugTomcat with IDEA && add VM option
"-Dspark.local=true"

* Load csv data source by pressing button "Data Source->Load CSV File as Table"
on "Model" page, and set the schema for your table. Then press "submit" to save.

Most time we debug just want to build and query cube easy. But current way is
complex to load csv tables and create model and cube. So, I want to add a csv
source which using the model of kylin sample data directly when debug tomcat
started.
