I am faced with a similar problem.
I want to process an entire set of bugs including their entire history.
Once. Then, incrementally process a combination of the latest output + the

I hit upon a way of handling multiple outputs. Perhaps if there was

The Java5 dependency is about to go from Hadoop. See HADOOP-7072. I

Hello,
I need to build hadoop in Linux as I need to make some small changes in the
code, but I don't know what is the simplest way to build hadoop. I googled it
and so far I only found two places that tell how to build hadoop. One is

3) The configuration (or lack thereof) on the machine you are trying to
run this, has no idea where your DFS or JobTracker is :)

Hi,
(1) I declared a global variable in my hadoop mainClass which gets
initialized in the 'run' function of this mainClass. When I try to access this

Hi Cavus,
Please check that hadoop JobTracker and other daemons are running by typing
"jps". If you see one of (JobTracker,TaskTracker,namenode,datanode) missing
then you need to 'stop-all' then format the namenode and start-all again.

Hello Cavus,
is your Job Tracker running on localhost? It would be great if you can
provide more information about your current Hadoop setup.
