[jira] [Comment Edited] (FLINK-20638) Flink hive modules Function with the same name bug

    [ https://issues.apache.org/jira/browse/FLINK-20638?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17251094#comment-17251094 ]

Hi [~HideOnBush], AFAIK, you can't use them both at the same time if name conflicts. 
You can reorder the priority of core module and hive module by using [loading and unloading modules API|https://ci.apache.org/projects/flink/flink-docs-master/dev/table/modules.html#loading-and-unloading-a-module], this can makes Flink load Hive module functions first. 

As an alternative, you can also use user defined function as [~zoucao] said.

> I want to use flink to use hive functions, after introducing hive modules, there are functions of the same name, Flink has a higher priority than Hive, the same function name, such as timestamp function, how do I distinguish between hive and Flink when using it?
