Subject [jira] [Updated] (HIVE-13903) getFunctionInfo is downloading jar on every call
Date Wed, 01 Jun 2016 09:35:59 GMT

     [ https://issues.apache.org/jira/browse/HIVE-13903?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rajat Khandelwal updated HIVE-13903:
------------------------------------
    Description: 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.
