Subject [jira] [Commented] (HIVE-13561) HiveServer2 is leaking ClassLoaders when add jar / temporary functions are used
Date Wed, 20 Apr 2016 21:58:25 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15250795#comment-15250795
] 

Trystan Leftwich commented on HIVE-13561:
-----------------------------------------

It looks to be that when calling CREATE TEMPORARY FUNCTION via JDBC through Hiveserver2, The
Function is still being created through the registerGenericUD*F methods:
https://github.com/apache/hive/blob/branch-1.2/ql/src/java/org/apache/hadoop/hive/ql/exec/Registry.java#L141

Which still uses the org.apache.hadoop.util.ReflectionUtils class.
