Hi,
We are usually here to help, but not really to do this all for you.
If you need someone to write this for you, there are some freelance sites
on the Internet where you can post a job or request and have people bid on
it.

One thing you might have to realize is that you will likely need to get
some kind of programming knowledge. You don't have to be an expert, but I
don't know that many orgs have dedicated Hadoop administrators that don't
have to touch some code at some point, even if to integrate components
togethe
You might want to consider the Hadoop course on udacity.com. I think it
provides a decent foundation to Hadoop/MapReduce with a focus on Python
(using the streaming API like Sebastiano mentions).

Note that the CDH link is for Cloudera which only provides Hadoop for Linux.
HDP has "pre-built VMs" for both Linux and Windows hosts.
You can also search for "HDInsight emulator" which runs on Windows and is based
on HDP.

It depends... It seems most are evolving from needing "lots of data
crunched", to "lots of data crunched right now". Most are looking for
*real-time* fraud detection or recommendations, for example, which
MapReduce is not ideal for.

I would consider the timeframe that you are looking for to determine if you
should focus on Hadoop 2.x (with YARN) or older. 2.x should scale much better
than 1.x.
Keep in mind that 2.x was only "officially" released late last year.

It is based on Java (uses Hortonworks), however, Microsoft provides a .NET SDK:

I'm a beginner and I'm having issues with MR when trying to read values of the
form 99.99.
I'm reading up as much as I can. I wanted to try to use Java's types to
determine whether to use a DoubleWritable or FloatWritable, but after some

Tom White's Hadoop book refers to old vs new MR APIs.
Is this strictly a MR1 vs MR2 (YARN) comparison, or something before MR2?
I'm pretty sure that site is illegal...

Hi.
I think you are asking for quite a bit without any indication that you have
tried to lookup this information yourself.
Start with your favourite search engine. and look for "hadoop firewall", for
example.
One example
http://docs.hortonworks.com/HDPDocuments/HDP1/HDP-1.2.0/bk_reference/
I'm not sure on your exact details, but it is always possible to do just
about anything with your MR logic.
Now, to suggests that there may or may not be a performance hit is a
different story...

Try something like:
http://tutorialgenius.blogspot.ca/2012/03/tcpdump-localhost.html
After you launch tcpdump it mentions "eth0", while your mapred-site.xml is
referring to "localhost" or "lo". Perhaps...
(Sorry, I don't have a VM running and can't remember if it's "lo" =
"elle-o".)

I'm assuming you can use Microsoft's .NET SDK to write to a non-HDInsight
cluster...

If you can't install 64-bit, simply install 32-bit. Basically, it means
you have access to a smaller amount of RAM, even if you're using a computer

You sort of need to break this down into first determining how to get Linux
on your systems.
RHEL is pretty costly for a test, unless you've got that covered. Go with
CentOS for a proo
You can try to search for "Rhadoop" using your favourite search engine.
I think you are going to have to put in a bit more effort on your own.

Hi Samir,
I may be alone here, but I would prefer you not use "urgent" when
asking for free help from a mailing list.
My recommendation is that if this is really urgent and you need
instant support for your Hadoop installation, that you consider
getting a proper support contract to help you when

examples of their admin training courses.
