NameNode Analytics 1.6.6

The thirteenth release of NameNode Analytics.

This is both a performance and feature release that adds two-level histograms, cached quota computation parallelization and includes the following:
[#285] Add query links for finding directories with no quotas
[#283] Add file type histogram to SuggestionsEngine
[#281] Improve cached quotas by using two level histograms
[#279] Provide histogram.html page
[#276] Add display for how many transactions NNA is behind
[#275] Provide easier restart functionality
[#267] Multi-level grouping in Stream API

It is recommended to update to this release as it has some serious performance improvements.

I recommend checking out the new /info information, the new auto-fetch image on restart functionality, the /fileTypes.html page, and playing around with the new /histogram.html and /histogram2.html pages.
