get format error for graph-data-generator

[Samaneh1986]

spark-bench_2.3.0_0.4.0-RELEASE

I get the below error when using spark-bench to generate graph data:

Exception in thread "main" java.lang.Exception: Unrecognized or unspecified save format. Please check the file extension or add a file format to your arguments

error happens in : verifyFormatOrThrow(SparkFuncs.scala:92)

You have said that "the Graph Data Generator can only output to .txt" but your "verifyFormat" function (SparkFuncs.scala:52) doesn't accept ".txt" !!!!

How can I use the Graph Data Generator? Is there any new release?

Thanks in advance,
