[jira] [Created] (HIVE-17524) instrument LLAP metadata cache with separate counters by format

Sergey Shelukhin created HIVE-17524:
---------------------------------------

             Summary: instrument LLAP metadata cache with separate counters by format
                 Key: HIVE-17524
                 URL: https://issues.apache.org/jira/browse/HIVE-17524
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


Followup from HIVE-15665. ORC file tails, Parquet file tails, and ORC stripe tails should be separately counted for jmx/iomem output. Technically cache should know nothing about what bytebuffer is what, so perhaps it should be by key type, and key types should be separated between the 3 more explicitly (including the replacement on Long HDFS inode based keys with 2 separate wrappers for primitive long).
