Description

In FLINK-1525 we've added the ParameterTool.

For users used to Hadoop's GenericOptionsParser it would be great to provide a compatible parser.

See: https://hadoop.apache.org/docs/r1.0.4/api/org/apache/hadoop/util/GenericOptionsParser.html

@Test
public void testFromGenericOptionsParser() {
	ParameterUtil parameter = ParameterUtil.fromGenericOptionsParser(new String[]{"-D", "input=myinput", "-DexpectedCount=15"});
	validate(parameter);
}
