Santhosh Srinivasan commented on PIG-1940:
------------------------------------------

Based on my preliminary analysis, the ExecutableManager.processError() method 
in o.a.p.impl.streaming needs to parse the reporter related output to access 
and subsequently increment counters (and possibly the status in the future). 
Access to the counters can be obtained through the 
PigStatusReporter.getInstance()

> Pig should support counters via stderr in streaming

> As of Pig version 0.7 streaming 
> http://wiki.apache.org/pig/PigStreamingFunctionalSpec does not support 
> status/counters as described in 
> http://hadoop.apache.org/common/docs/r0.20.2/streaming.html#How+do+I+update+counters+in+streaming+applications%3F.
>   Would be very nice to have this functionality.
