Eric Wohlstadter commented on HIVE-19682: ----------------------------------------- [~prasanth_j] Can you check? > Provide option for GenericUDTFGetSplits to return only schema metadata > ---------------------------------------------------------------------- > > Key: HIVE-19682 > URL: https://issues.apache.org/jira/browse/HIVE-19682 > Project: Hive > Issue Type: Improvement > Reporter: Eric Wohlstadter > Assignee: Eric Wohlstadter > Priority: Major > Attachments: HIVE-19682.1.patch > > > For some uses cases it is necessary to know the output schema for a HiveQL > before executing the query. But there is no existing client API that provides > this information. > Hive JDBC doesn't provide the schema for parametric types in > {{ResultSetMetaData}}. > GenericUDTFGetSplits bundles the proper schema metadata with the fragments > for input splits. An option can be added to return only the schema metadata > from compilation, and the generation of input splits can be skipped. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
