11 years ago Hi Amer,
Great to hear it's helping you get a start. Unfortunately there isn't a lot of documentation around it and we haven't had a chance yet to really crank up its use.
Here is a quick example of one of our test cases we used with Ape:
!/home/y/bin/perl5.10
use Ape;
while (true) {
Get a random slaves
$host = Ape::getRandomSlave("slaves"); # Corrupt 5 hdfs blocks on that slave
Ape::ape([true, $host, "-C", "ord 1024 10"]);
Ape::ape([true, $host, "-C", "ord 1024 10"]);
Ape::ape([true, $host, "-C", "ord 1024 10"]);
Ape::ape([true, $host, "-C", "ord 1024 10"]);
Ape::ape([true, $host, "-C", "ord 1024 10"]);
$port = '8020';
$duration = '10';
@slaves = Ape::getSlaves("slaves");
$slavestring = join(" ", @slaves);
# Emulate high network traffic
Ape::ape([true, $slavestring, "-u", "<namenode hostname>" . ' ' . $port . ' ' . $duration]);
sleep int(rand(60));}
This script corrupts 5 random hdfs data blocks on a single host, then bombards the NameNode with a DDoS?http://twiki.corp.yahoo.com/edit/Hadoop/DDoS?topicparent=Hadoop.FaultInjectionTestingJournal;nowysiwyg=1 attack originating from each DataNode.

Hi Nathan, I am currently working on my final year thesis at National ICT Australia. The main focus of this thesis is to investigate how an AWS-based Hadoop ecosystem behaves under different types of faults which occur in public cloud.
I came across your repo which was really helpful to get my project started. I have successfully compiled AnachyApe but I am not sure how to use it. So I was hoping if you would be able to share your source code or documents of how your team used it.
Regards,
Amer Abdalamer
