Subject [jira] [Updated] (HIVE-11595) refactor ORC footer reading to make it usable from outside
Date Fri, 28 Aug 2015 17:55:45 GMT

     [ https://issues.apache.org/jira/browse/HIVE-11595?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sergey Shelukhin updated HIVE-11595:
------------------------------------
    Attachment: HIVE-11595.04.patch

Some more small fixes from metastore branch. ORC allocates a new buffer so patch 03 code works
on normal path, but in case of non-0 position it breaks (i.e. when footer comes from HBase
response w/o copy). This fixes these issues.

> If ORC footer is read from cache, we want to parse it without having the reader, opening
a file, etc. I thought it would be as simple as protobuf parseFrom bytes, but apparently there's
bunch of stuff going on there. It needs to be accessible via something like parseFrom(ByteBuffer),
or similar.
