Xiaochen Ouyang commented on SPARK-20383: ----------------------------------------- [~cloud_fan] Hello, whether the type of this issue can be changed to New feature? > SparkSQL unsupports to create function with the keyword 'OR REPLACE' and 'IF > NOT EXISTS' > ---------------------------------------------------------------------------------------- > > Key: SPARK-20383 > URL: https://issues.apache.org/jira/browse/SPARK-20383 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.0.0, 2.0.2, 2.1.0 > Environment: spark2.1.0 > Reporter: Xiaochen Ouyang > Assignee: Xiaochen Ouyang > Fix For: 2.3.0 > > > unsupport to create a temporary|permanent function with the key word 'IF NOT > EXISTS'. > I think it is necessary to support this key word in 'create [temporary] > fucntion ...' clause, > For example: > I hava an application which has three steps as follow : > 1. insert into table t1 as select id from t where ... > 2. create function AA as ... using jar ... > 3. insert into table t2 select AA(id) from t1 > my application run succussfully first time and it will throw an exeception at > step 2 when it run again. So, I think it is reasonable and friendly to user > application. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
