Jason Dere created HIVE-13586: --------------------------------- Summary: Allow UDFs/UDTFs to indicate whether they can run with fetch task conversion Key: HIVE-13586 URL: https://issues.apache.org/jira/browse/HIVE-13586 Project: Hive Issue Type: Bug Components: UDF Reporter: Jason Dere Assignee: Jason Dere
Some UDFs/UDTFs cannot run properly with fetch task conversion. For UDFs: - The UDF may be depending on files/archives added to the distributed cache, which may not be available in the local fetch task. - The UDF may be depending on GenericUDF.configure() to be called - this is not called for locally run UDFs. For UDTFs, one issue is HIVE-11892. A bit of a workaround, but for such UDFs/UDTFs we can have a flag to indicate whether the UDF should be allowed to run in a local fetch task. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
