Subject [jira] [Commented] (HIVE-5814) Add DATE, TIMESTAMP, DECIMAL, CHAR, VARCHAR types support in HCat
Date Mon, 19 May 2014 18:52:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5814?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14002163#comment-14002163
] 

Eugene Koifman commented on HIVE-5814:
--------------------------------------

org.apache.hcatalog.pig.HCatLoader has been deprecated in Hive 0.12.
In fact every class in org.apache.hcatalog has been deprecated.  All new features are added
in org.apache.hive.hcatalog which contains all the classes/methods from org.apache.hcatalog
and new APIs.

> Hive 0.12 added support for new data types.  Pig 0.12 added some as well.  HCat should
handle these as well.    Also note that CHAR was added recently.
> Also allow user to specify a parameter in Pig like so HCatStorer('','', '-onOutOfRangeValue
Throw') to control what happens when Pig's value is out of range for target Hive column. 
Valid values for the option are Throw and Null.  Throw - make the runtime raise an exception,
Null, which is the default, means NULL is written to target column and a message to that effect
is emitted to the log.  Only 1 message per column/data type is sent to the log.
> See attached HCat-Pig Type Mapping Hive 0.13.pdf for exact mappings.
