             Summary: Debug the code of Kylin on Parquet without hadoop environment
                 Key: KYLIN-4625

          Issue Type: Improvement
          Components: Spark Engine

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.
