"CarbonStreamSparkStreamingExample.scala" introduces how to use Spark
Streaming to write data to stream table, and "CarbonBatchSparkStreamingExample"
introduces how to use Spark Streaming to write data to batch loading table
which will auto compact segment. There are some different configurations and
process flow, so I think using two examples is more clear.
