> The regionserver status page, such as http://127.0.0.1:60030/rs-status always downloads information about every bucket in the cache. In some cases this can be hundreds of thousands of buckets, causing megabytes of info to need to be downloaded and significant browser instability and memory usage:

> ls -lah HBase-Region-Server-hb22.html
> 32M Oct 6 19:23 HBase-Region-Server-hb22.html
> Firefox "about:memory":
> 1,330.18 MB (48.22%) -- top(http://hb22:60030/rs-status#bc_l2, id=2010)
> 1,329.61 MB (48.20%) -- active/window(http://hb22:60030/rs-status#bc_l2)
