             Summary: Improve the 'Too many blocks' message on UI blockcache 
status page
                 Key: HBASE-11697
                 URL: https://issues.apache.org/jira/browse/HBASE-11697
             Project: HBase
          Issue Type: Improvement
            Reporter: Andrew Purtell
            Priority: Minor
             Fix For: 0.99.0, 2.0.0, 0.98.6
         Attachments: TooManyBlocks.png

If metrics calculations over blockcache contents stopped after examining 
hbase.ui.blockcache.by.file.max items, the UI will put up a message. However, 
this notion of "too many blocks" / fullness refers to structures used for 
calculating blockcache metrics. See BlockCacheUtil. We should improve this 
message so it does not leave a user the impression the blockcache may be in a 
bad state.
