> Currently, Kylin on Parquet already supports debuging source code with local
> csv files and Not dependent on remote HDP sandbox, but it's a little bit
> complex. The steps are as follows:
> * edit the properties of
> $KYLIN_SOURCE_DIR/examples/test_case_data/sandbox/kylin.properties to local
> {code:java}
> kylin.metadata.url=$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
> kylin.env=UT{code}
> * 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 quickly and focus the
> bug we want to resolve. But current way is complex to load csv tables, create
> model and cube and it's hard to use kylin sample cube. So, I want to add a
> csv source which using the model of kylin sample data directly when debug
> tomcat started.
