--------------------------------
Summary: Support better entropy performance on vagrant VMs
Key: BIGTOP-1347
URL: https://issues.apache.org/jira/browse/BIGTOP-1347
Project: Bigtop
Issue Type: Improvement
Components: Deployment
Affects Versions: 0.7.0
Reporter: Evans Ye
Priority: Minor
Fix For: 0.8.0
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.
