dengkai updated FLUME-3044:
---------------------------
    Description: 
There are several method call in kafka sink with no timeout arguments, in some 
cases, kafka sink will await forever if no interruption. 
For example,
case 1 : 
case 2 : 
case 3 : When an odd exception happened such as Correlation ID does not match 
in Kafka Producer Sender thread, the sender will lost this request. If we call 
producer.flush(), there is a await() without timeout arguement, kafka sink will 
block all the time except restart it.
