Sergey Shelukhin updated HIVE-14453:
------------------------------------
Description:
ORC data doesn't have to go directly into an HDFS stream via buffers, it can go
somewhere else (e.g. a write-thru cache, or an addressable system that doesn't
require the stream blocks to be held in memory before writing them all
together).
To that effect, it would be nice to abstract the data block/metadata structure
creating from the physical file concerns.
> refactor physical writing of ORC data and metadata to FS from the logical
> writers
