[jira] [Created] (IMPALA-8884) Track Read(), Open() and Write() operation time per disk queue

Tim Armstrong created IMPALA-8884:
-------------------------------------

             Summary: Track Read(), Open() and Write() operation time per disk queue
                 Key: IMPALA-8884
                 URL: https://issues.apache.org/jira/browse/IMPALA-8884
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


It would be useful for debugging I/O performance problems if we had histogram stats for the time taken for various operations so that we could see if there were slow operations on a particular disk (e.g. because of disk failure) or from a particular remote filesystem.
