AWS EMR stuck bootstrapping
<p>For a course, we are doing a basic tweet analysis using AWS EMR. I followed the steps in this document:
<a href="http://docs.aws.amazon.com/en_us/gettingstarted/latest/emr/awsgsg-emr.pdf" rel="nofollow">http://docs.aws.amazon.com/en_us/gettingstarted/latest/emr/awsgsg-emr.pdf</a></p>

<p>The only modifications are that I uploaded a pre-done set of tweets and we are told to use our own config file for the NLTK. The instructor gave us the following for the custom NLTK config:</p>

<pre><code>#!/bin/bash 
sudo yum -y install git gcc python-dev python-devel
sudo ln -sf /usr/bin/python2.7 /usr/bin/python
sudo easy_install pip
sudo pip install -U numpy
sudo pip install numpy
sudo easy_install -U distribute
sudo pip install -U setuptools
sudo pip install pyyaml nltk 
sudo pip install -e git://github.com/mdp-toolkit/mdp-toolkit#egg=MDP 
sudo python -m nltk.downloader -d /usr/share/nltk_data all 
</code></pre>

<p>I create my cluster and, when it executes, it gets to 'bootstrapping' and has been stuck there for 45 minutes. Using AMI Version 3.11.0, no Hive, Pig, or HUE.</p>

<p>Please let me know if more information is needed to try to diagnose this. What could cause this?</p>
