> Hadoop Streaming supports the ability to update counters and status by writing specially coded messages to the script's stderr stream.
> A streaming process can use the stderr to emit counter information. {{reporter:counter:<group>,<counter>,<amount>}} should be sent to stderr to update the counter.
> A streaming process can use the stderr to emit status information. To set a status, {{reporter:status:<message>}} should be sent to stderr.
> Hive should support these same features with its TRANSFORM mechanism.
