<section name="Whirr&#153; Know Limitations"></section>
<p>We are striving to make each release as good as possible but there are still a set of
limitations that you should be aware of. The following issues are known to exist in the 0.8.0 release of Whirr.</p>
<ul>
<li>When launching an HBase 0.92.0 or 0.92.1 cluster, the regionserver may not launch properly if the master is not already up. Start the regionserver service again after the master is up. This is a bug in HBase, fixed in the upcoming 0.92.2.</li>
<li>The order of the roles is significant. (e.g. hadoop-jobtracker+hadoop-namenode will try to start the jobtracker before starting the namenode)</li>
<li>The "jclouds.aws-s3.endpoint" property is needed in order to use BlobCache with Amazon AWS in a region besides us-east-1. See <a href="https://issues.apache.org/jira/browse/WHIRR-349#comment-13084590">WHIRR-349</a> for more details</li>
</ul>
