[jira] [Created] (HIVE-2916) Hive Type Information for Table
Columns
Hive Type Information for Table Columns
---------------------------------------
Key: HIVE-2916
URL: https://issues.apache.org/jira/browse/HIVE-2916
Project: Hive
Issue Type: Bug
Environment: Hive-0.8.1
Reporter: Indrani Gorti
Priority: Blocker
Hi
I am using Hive-0.8.1. I am trying to get type information for table columns from MetaStore. The Developer documentation says the components of ql/typeinfo is responsible for this.
i.e, under the query processor section in https://cwiki.apache.org/confluence/display/Hive/DeveloperGuide#DeveloperGuide-QueryProcessor
However the directory "typeinfo" is missing in hive.I understand from typeinfo has java files that is responsible for getting all struct fieldnames, categories, primitive types. etc.

Indrani Gorti resolved HIVE-2916.
---------------------------------
Resolution: Fixed
Fix Version/s: 0.8.0
0.8.1
Hi
I just realized that there is a package
"org.apache.hadoop.hive.serde2.typeinfo" that is imported when file q/typeinfo has to be used.
The package has the following which is what /q/typeinfo directory contains
* ListTypeInfo.java
* MapTypeInfo.java
* PrimitiveTypeInfo.java
* StructTypeInfo.java
* TypeInfo.java
* TypeInfoFactory.java
* TypeInfoUtils.java
one can see this in
http://hive.apache.org/docs/r0.7.1/api/org/apache/hadoop/hive/serde2/typeinfo/package-tree.html
and
https://svn.apache.org/repos/asf/hive/branches/branch-0.2/ql/src/java/org/apache/hadoop/hive/ql/typeinfo/
