----------------------------------
Hi [~jeid], actually haveged is the first tool I tried to solve this and it
also works well during my test.
But after doing some investigation I found that rng-tools have less setup steps
and is more common than haveged, for example, rng-tools is built-in in our
default vagrant box.
Since the intention of this Jira is to move the blocking rock out of the road
when we're going to test our puppet recipes or providing a sample hadoop
environment. So I would say that keeping things simpler is better.
Another thought in my mind is that the we don't know when will the download
link of haveged out of available in the future, and since haveged is in GPL
license, we probably can not store it as one of our provisioning library.
Please feel free to correct me if I get anything wrong:)

> Currently the
> [vagrant-puppet|https://github.com/apache/bigtop/tree/master/bigtop-deploy/vm/vagrant-puppet]
> deployment use Virtualbox as VM provider. The visualized hardware in
> Virtualbox does not have good performance on entropy generation since such
> randomness often collected from hardware sources.
> The poor entropy performance directly impact the use in cryptography or use
> that required random data, which in our case is kerberos. In order to test
> our code snipes for real world usage instead of suffering on virtual
> machines, we can improve the entropy performance on VMs using rng-tools when
> provisioning those test VMs.
