The front end messages are logged to the Pig log. In MR mode, the backend 
messages are logged in the logs of the map and reduce tasks, not in the Pig 
log. In local mode, the backend messages are displayed on the console. 

You can find how long the execution of a query took in the Pig log.

The conf/log4j.properties is not used by default, if you want to use it, you 
need explicitly specify the command line option: -4 conf/log4j.properties.

The default log level is INFO, to change this, you need to use the command line 
option: -d DEBUG.

Thanks,
-Richard

Hi,

where can I find informations about how the Logging of PIG works?
Does PIG generate Log-Files like how long the execution of a query took and 
where can I find them?

Thx in advance.

Alex
