Spark directory:
```
./bin/spark-shell --conf

**NOTE**
- In this flow, we can use the built-in SparkSession `spark` instead of
`carbon`.
We also can create a new SparkSession instead of the built-in SparkSession
`spark` if need.
It need to add "org.apache.spark.sql.CarbonExtensions" into spark
configuration "spark.sql.extensions".
