Subject [jira] [Commented] (HBASE-14582) Regionserver status webpage bucketcache list can become huge
Date Wed, 21 Oct 2015 16:29:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14967397#comment-14967397

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.

> 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)
