Anton Vinogradov commented on IGNITE-3303:
------------------------------------------

Saikat, 

1) Seems you fix not works. 

I set brakepoint at before last test and I see a lot of theads at {{IgniteSource.run}} 
{noformat}
"Source: Custom Source -> Sink: Unnamed (1/1)@6026" daemon prio=5 tid=0x7e nid=NA runnable
  java.lang.Thread.State: RUNNABLE
	  at org.apache.ignite.source.flink.IgniteSource.run(IgniteSource.java:153)
	  at org.apache.flink.streaming.api.operators.StreamSource.run(StreamSource.java:78)
	  at org.apache.flink.streaming.runtime.tasks.SourceStreamTask.run(SourceStreamTask.java:56)
	  at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:224)
	  at org.apache.flink.runtime.taskmanager.Task.run(Task.java:559)
	  at java.lang.Thread.run(Thread.java:745)
{noformat}

In other works in first test we have 1 {{IgniteSource}}, in second we have 2 and so on. This
seems to be not what we expected.

As I told before {{IgniteSource.cancel()}} will not stop {{IgniteSource}} in case it runned
from test. It should be runned from {{StreamExecutionEnvironment}} somehow. 

Please fix this and make sure that tests work properly.
Btw, we can discuss this by skype before fixing.
