Re: Doubt regarding debugging Hadoop Classes

2012-07-02 Thread Harsh J
As far as I can tell, the Fetcher class executes from within a Task JVM. So check your reduce's userlogs output instead of the service's/daemon's logs. Additionally, depending on what version of Hadoop you're using for your project, try this: http://search-hadoop.com/m/SKajPZOkJa1 On Tue, Jul 3,

Another way is to use Java remove debugging feature, which allows you to keep your IDE and source code locally and run a Hadoop daemon with a couple extra JVM flags to bring up debug server within the process. On Wed, Jan 26, 2011 at 09:22, Steve Loughran wrote: > On 23/01/11 06:31, Zinab Ahmed M
