[ https://issues.apache.org/jira/browse/HIVE-2916?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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/

> 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 hadoop/hive/ql.I understand from typeinfo has java files that is responsible for getting all struct fieldnames, categories, primitive types. etc.
