Subject [jira] [Updated] (SPARK-23122) Deprecate register* for UDFs in SQLContext and Catalog in PySpark
Date Mon, 22 Jan 2018 06:32:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-23122?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Xiao Li updated SPARK-23122:
----------------------------
    Description: 
Deprecate register* for UDFs in SQLContext and Catalog in PySpark

Seems we allow many other ways to register UDFs in SQL statements. Some are in {{SQLContext}} and
some are in {{Catalog}}.

These are also inconsistent with Java / Scala APIs. Seems we better deprecating them and put
the logics into {{UDFRegistration}} ({{spark.udf.register*}}).

Please see this discussion too - [https://github.com/apache/spark/pull/20217#issuecomment-357134926].
