Prasanth J commented on HIVE-6060:
----------------------------------
[~owen.omalley] HIVE-6578 added support for partialscan and noscan support in
analyze statement for ORC files. When analyze command with partial or noscan is
executed, each partition directory is iterated, creating ORC readers for files
under the each directory. Basic statistics like number of rows, file size, raw
data size are computed by reading stats from ORC file footer. How does
HIVE-5317 and HIVE-6060 changes affect HIVE-6578 way of stats gathering?
> Define API for RecordUpdater and UpdateReader

> We need to define some new APIs for how Hive interacts with the file formats
> since it needs to be much richer than the current RecordReader and
> RecordWriter.
