Hi, @haohao0103, thanks for your work, but -1 for me.
I tested locally use `./bin/hugegraph-spark-loader.sh --master local[*]
--name spark-hugegraph-loader --file ./example/spark/struct.json --host
192.168.34.164 --port 18080 --graph hugegraph`
but got:
```
java.lang.NullPointerException
at java.lang.String.split(String.java:2337)
at java.lang.String.split(String.java:2422)
```
If I remember correctly, delimieter has a default comma, we need to check
this?
```
elements = builder.build(fileSource.header(),
row.mkString(delimiter).split(delimiter));
```
