Date Thu, 08 Oct 2015 20:42:26 GMT
James Hartshorn created HBASE-14582:

             Summary: Regionserver status webpage bucketcache list can become huge
                 Key: HBASE-14582
                 URL: https://issues.apache.org/jira/browse/HBASE-14582
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: James Hartshorn
            Priority: Trivial

The regionserver status page, such as 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:
