Subject Re: MAPREDUCE-4394 PATCH submission
Date Thu, 30 May 2013 17:27:37 GMT
Hi Deepak,

As I am also very new to Hadoop and am still learning (don't really know
when I will become an expert like the other experts,may take years!!) , but
am trying very hard. But, yes I can share you my experience on  how I
started , actually  this patch was my second patch submission.
Coming to 'How to start contributing and learning Hadoop' (Please note that
this is my view, others may disagree or may add a few points if needed)

1. Go to this link http://wiki.apache.org/hadoop/HowToContribute. Read what
is given on this page.
2. On this page there is a link 'ProjectSuggestions' , click this link and
you will find another link 'Newbie Jiras' click that and you will find
dozens of unresolved bugs. Pick up one which you find the easiest , make
the changes . I hope you know how to use svn to checkout and to create
patches, if you don't know it is given on the link which I've mentioned at
number 1.

This is the learning and understanding part of Hadoop architecture.
1. Get hold of that book by Tom White ' Hadoop The Definitive Guide' and
read the HDFS and MAP REDUCE section line by line, it's worth a goldmine.
2. Subscribe to every mailing list of Hadoop eg. Users,issues,dev etc. and
read what others are talking about , you will find lots and lots of useful
stuff.
3. If you have any doubts regarding any feature HDFS,MAPREDUCE,COMMON,YARN
etc , shoot a mail for help but be precise on what you want to know and
what difficulty you are facing and in which feature.

As Hadoop is large , it can be overwhelming , I don't know for others but
for me it certainly is and I am still reading the source code of Hadoop and
Tom White's book side by side. Sometimes I get and sometimes I don't.

A  lot depends on your experience and exposure to large frameworks(may be
in your company) and if you have fixed issues earlier it will be a lot
easier.

Regards,
Niranjan Singh
