Re: How to add debugging to map- red code

I tried: public class TestMapper extends Mapper { private String numericRegEx = "(-|\\+)?[0-9]+"; static Logger logger = Logger.getLogger(TestMapper.class); public void setup(Context context) throws IOException, InterruptedException { conf = context.getConfiguration(); org.apache.log

Re: How to add debugging to map- red code

here is a sample code from log4j documentation if you want to specify a specific file where you want to write the log .. you can have a log4j properties file and add it to the classpath import com.foo.Bar; // Import log4j classes. *import org.apache.log4j.Logger; import org.apache.log4j.Basic

Re: How to add debugging to map- red code

Hi Harsh, Could you show one sample of how to do this ? I have not seen/written any mapper code where people use log4j logger or log4j file to set the log level. Thanks in advance -JJ On Thu, May 3, 2012 at 4:32 PM, Harsh J wrote: > Doing (ii) would be an isolated app-level config and wouldn'

Thanks Harsh. Are they in cdh3 too ? On Thu, May 3, 2012 at 4:32 PM, Harsh J wrote: > Doing (ii) would be an isolated app-level config and wouldn't get > affected by the toggling of > (i). The feature from (i) is available already in CDH 4.0.0-b2 btw. > > On Fri, May 4, 2012 at 4:58 AM, Mapre

Re: How to add debugging to map- red code

(Shit, sorry about my last response, I got confused and thought this were a cdh-user list. I deeply apologize.) The (i) is in 0.23.1/2.x if you upgrade to that today. On Fri, May 4, 2012 at 5:02 AM, Harsh J wrote: > Doing (ii) would be an isolated app-level config and wouldn't get > affected by

Re: How to add debugging to map- red code

Doing (ii) would be an isolated app-level config and wouldn't get affected by the toggling of (i). The feature from (i) is available already in CDH 4.0.0-b2 btw. On Fri, May 4, 2012 at 4:58 AM, Mapred Learn wrote: > Hi Harsh, > > Does doing (ii) mess up with hadoop (i) level ? > > Or does it happ

Re: How to add debugging to map- red code

Hi Harsh, Does doing (ii) mess up with hadoop (i) level ? Or does it happen in both the options anyways ? Thanks, -JJ On Fri, Apr 20, 2012 at 8:28 AM, Harsh J wrote: > Yes this is possible, and there's two ways to do this. > > 1. Use a distro/release that carries the > https://issues.apache.

Re: How to add debugging to map- red code

I'm interested in this too, but could you tell me where to apply the patch and is the following the right command to write it: patch < MAPREDUCE-336_0_20090818.patch

Re: How to add debugging to map- red code

Yes this is possible, and there's two ways to do this. 1. Use a distro/release that carries the https://issues.apache.org/jira/browse/MAPREDUCE-336 fix. This will let you avoid work (see 2, which is same as your idea) 2. Configure your implementation's logger object's level in the setup/setConf m

How to add debugging to map- red code

Hi, I m trying to find out best way to add debugging in map- red code. I have System.out.println() statements that I keep on commenting and uncommenting so as not to increase stdout size But problem is anytime I need debug, I Hv to re-compile. If there a way, I can define log levels using log4j
