[jira] [Created] (IMPALA-5166) Clean up BufferPool profile counters

Tim Armstrong created IMPALA-5166:
-------------------------------------

             Summary: Clean up BufferPool profile counters
                 Key: IMPALA-5166
                 URL: https://issues.apache.org/jira/browse/IMPALA-5166
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend
    Affects Versions: Impala 2.9.0
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


We should clean-up the profile counters that are added to each node so that irrelevant info is hidden and relevant info is easy to find:
- Hide the limit if it is MAX_INT64
- Remove the BufferPool prefix and move into a "Buffer pool" section, or similar
- Remove or rename potentially confusing counters, e.g. 
-- the cumulative allocation counters should be removed or renamed to be clearer that they are cumulative
-- PeakUnpinnedBytes is confusing unless you understand the internals
