Subject How to make changes in Hadoop's classes "visible"
Date Fri, 29 Apr 2011 15:40:00 GMT

I am a beginner and I have downloaded Hadoop 0.20.2.
I would like to make some changes in some of the classes of Hadoop and import them into hadoop-0.20.2-core.jar
so that they are visible to the mapreduce programs. 
What is the best way to do this?
What should I do if I find the changes at JIRA, for example if I want to change the LoadIncrementalHFiles
class as mentioned at https://issues.apache.org/jira/browse/HBASE-3714?
Is it the same procedure?

Thank you in advance!!
