Lefty Leverenz commented on HIVE-9917:
--------------------------------------

Doc note:  This adds *hive.int.timestamp.conversion.in.seconds* to 
HiveConf.java, so it needs to be documented in Configuration Properties.

It could also be mentioned in the Timestamps section of Data Types (with 
version information).

* [Hive Data Types -- Timestamps | 
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Types#LanguageManualTypes-Timestamps]
* [Configuration Properties -- Query and DDL Execution | 
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution]

> After HIVE-3454 is done, make int to timestamp conversion configurable

> After HIVE-3454 is fixed, we will have correct behavior of converting int to 
> timestamp. While the customers are using such incorrect behavior for so long, 
> better to make it configurable so that in one release, it will default to 
> old/inconsistent way and the next release will default to new/consistent way. 
> And then we will deprecate it.
