Sergey Shelukhin reassigned HIVE-17524:
---------------------------------------
> 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).
