[jira] [Commented] (HIVE-10616) TypeInfoUtils doesn't handle DECIMAL with just precision specified

["Jason Dere (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-10616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16067269#comment-16067269 ] 

Jason Dere commented on HIVE-10616:
-----------------------------------

A bit late to the dance here, but the behavior here is definitely odd, should be either
1) correctly parse decimal(precision)
2) raise an error because decimal(precision, scale) is required
Returning decimal(10,0) in this case is just wrong - if we do make a change, might as well use [~tfriedr]'s patch. Do you mind adding a testcase to TestTypeInfoUtils for this?

> The parseType method in TypeInfoUtils doesn't handle decimal types with just precision specified although that's a valid type definition. 
> As a result, TypeInfoUtils.getTypeInfoFromTypeString will always return decimal(10,0) for any decimal(<precision>) string.
