Dale LaBossiere commented on EDGENT-310:
----------------------------------------

The problem is that the gradle harness isn't passing along the -D args to the 
separate JVM it spawns to run the tests.
See the fix in https://github.com/apache/incubator-edgent/pull/260

With that change I started my kafka server and zk on non-default ports (9093 
and 2182 respectively), created the test topics, and then successfully ran the 
kafka connector tests with:
```
./gradlew connectors:kafka:test --tests '*.*Manual' 
-Dorg.apache.edgent.test.connector\
s.kafka.bootstrap.servers=localhost:9093 -Dorg.apache.edgent.test.connectors.ka\
fka.zookeeper.connect=localhost:2182
```

> KafkaStreamsTestManual.testSimple() fails with no local zk or kafka servers

>          Issue Type: Test
>          Components: Test
>    Affects Versions: Apache Edgent 1.0.0

> I have set up a kafka on local and a remote machine following the quick start 
> guide http://kafka.apache.org/quickstart. And I pulled the latest code of the 
> branch "release1.0.0". I tried to run KafkaStreamsTestManual.testSimple(), 
> but found it works with local kafka but fails with the remote kafka (the 
> error shown as below ). I have tested my remote kafka with my local kafka 
> console client and the SimpleSubscriberApp.java so I am sure that it works. 
> And I even tried to start local kafka consumer console client during 
> testSimple() is running, I can get the messages ('Hello' and 'Are you 
> there?') from the console. So I am suspecting that there is something wrong 
> with Edgent Tester to handle this test case.
