Recently I've been working with Sensu and learning how awesome it is to have collected data available from | |
Sensu's built-in API. While building an internal dashboard by embedding graphite graphs into a xwiki page this afternoon, I | |
thought why not add a [stashboard](http://www.stashboard.org) like block element to the dashboard as I have API access to the | |
Sensu data. Stashboard is something I've always admired for it's and ability to display status to an audience that doesn't | |

The httpfs gateway is a proxy that allows users to read & write data using webhdfs. The benefit is httpfs behaves as a choke point by preventing access to the namenode and datanode ports. While looking into load issues for a single httpfs gateway, I started thinking why can't we bring up multiple httpfs gateways and put a layer7 load balancer in front?
To experiment, I downloaded an apache hadoop 2.7.1 binary package and followed the single node pseudo distributed node instructions to get a cluster running on my Mac. My next step was to add hadoop proxy settings for the httpfs gateway to core-site.xml. For example:
<property>
<name>hadoop.proxyuser.root.hosts</name>
<value>*</value>
