Jason Dere commented on HIVE-13903: ----------------------------------- Hi [~prongs], just trying to get a little background on this one - was the JAR being downloaded once per session, or was it getting downloaded every time the UDF was being used, even in the same session? > getFunctionInfo is downloading jar on every call > ------------------------------------------------ > > Key: HIVE-13903 > URL: https://issues.apache.org/jira/browse/HIVE-13903 > Project: Hive > Issue Type: Bug > Reporter: Rajat Khandelwal > Assignee: Rajat Khandelwal > Fix For: 2.1.0 > > Attachments: HIVE-13903.01.patch, HIVE-13903.01.patch, > HIVE-13903.02.patch > > > on queries using permanent udfs, the jar file of the udf is downloaded > multiple times. Each call originating from Registry.getFunctionInfo. This > increases time for the query, especially if that query is just an explain > query. The jar should be downloaded once, and not downloaded again if the udf > class is accessible in the current thread. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
