James Hartshorn commented on HBASE-14582:
-----------------------------------------
I've tested this patch and are quite pleased with it. Region server status
pages load instantly and browser memory usage is completely reasonable (8MB
when I checked). Thank you very much.
> Regionserver status webpage bucketcache list can become huge

> 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:
> wc -l HBase-Region-Server-hb22.html
> 2010116 HBase-Region-Server-hb22.html
> 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)
