Hari Shreedharan commented on SQOOP-738:
----------------------------------------

Jarcec,

Why do you think the consumer is not waited on? I looks like it is. The 
free.acquire call blocks this thread until the consumer thread has done 
free.release(), which it does only after processing the data in the pipeline. 
It looks ok to me.

> I've tried to import exactly 408,957 (nice rounded number right?) rows in 10 
> mappers and I've noticed that not all mappers will supply all the data all 
> the time. For example in run I got 6 files with expected size of 10MB whereas 
> the other 4 random files are completely empty. In another run I got 8 files 
> of 10MB and just 2 files empty. I did not quite found any logic regarding how 
> many and which files will end up empty. We definitely need to address this.
