>                 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).
