Lefty Leverenz commented on HIVE-5728:
--------------------------------------
This added four configuration parameters to HiveConf.java in 0.13.0.
* *hive.exec.orc.default.row.index.stride*
* *hive.exec.orc.default.buffer.size*
* *hive.exec.orc.default.block.padding*
* *hive.exec.orc.default.compress*
Note that the first parameter the patch changes just adds a line break --
*hive.exec.orc.dictionary.key.size.threshold* was added by HIVE-4324 in 0.12.0.
The four new parameters are documented in the wiki here:
* [Configuration Properties -- hive.exec.orc.default.row.index.stride |

> ORC InputFormat/OutputFormat is currently not usable outside Hive. There are
> several issues need to solve:
> 1. Several class is not public, eg: OrcStruct
> 2. There is no InputFormat/OutputFormat for new api (Some tools such as Pig
> need new api)
> 3. Has no way to push WriteOption to OutputFormat outside Hive
