---------------------------------------
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 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:
