Hi All,
I am facing sort of a weird issue in YARN. I am running a
single container on a cluster whose cpu configuration is as follows:
Try docker!

Hi daemon: Actually, for most folks who would want to actually use a
hadoop cluster, i would think setting up bigtop is super easy ! If you
have issues with it ping me and I can help you get started.
Also, we have docker containers - so you dont even *need* a VM to run a 4

Hi Fabio,
To answer your questions:
1)
CS (capacity-scheduler) will do allocation from root to leaf, level by
level, and for queues with same parent, will do allocation in following way:
First will allocate queue with least used resource
If queues with same used resource, say root.qA used 1G, root.
What you want as a sandbox depends on what you are trying to learn.
If you are trying to learn to code in e.g PigLatin, Sqooz, or similar, all
of the suggestions (perhaps excluding BigTop due to its setup complexities)
are great. Laptop? perhaps but laptop's are really kind of infuriatingly
slow (
you can try the pivotal vm as well.

Or on your local laptop or desktop you can setup the env using VM and VM
image of Hadoop and related components. Wrote instructions sometime back

Hello Tim,
Horton and Cloudera both offer VM’s (Including Virtual box, which is free) you
can pull down to play with, if you’re looking just for something small to get
you started. i’m partial to the horton works one myself.
Hope that help.

Tim,
download Sandbox from http://hortonworks/com
You will have everything needed in a small VM instance which will run on
your home desktop.
*Thank you!*

Hi tim. Id suggest using apache bigtop for this.
BigTop integrates the hadoop ecosystem into a single upstream distribution,
packages everything, curates smoke tests, vagrant, docker recipes for
deployment.
Also, we curate a blueprint hadoop application (bigpetstore) which you
build yourself, eas

Hey all,
I want to setup an environment where I can teach myself hadoop. Usually
the way I'll handle this is to grab a machine off the Amazon free tier and
setup whatever software I want.
However I realize that Hadoop is a memory intensive, big data solution. So
what I'm wondering is, would a t2
