[jira] [Commented] (HIVE-24636) Memory leak due to stacking UDFClassLoader in Apache Commons LogFactory

    [ https://issues.apache.org/jira/browse/HIVE-24636?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17271554#comment-17271554 ]

--------------------------------------

Hi [~dohongdayi], appreciate the patch, but I think the project now uses github pull requests, not patch files. In any case, this is not resolved fixed, since it has not been reviewed and merged by a committer. Do you need help pushing this through the process?

> Much the same as [HIVE-7563|https://issues.apache.org/jira/browse/HIVE-7563], after ClassLoader is closed in JavaUtils, it should be released by Apache Commons LogFactory, or the ClassLoader can't be Garbage Collected, which leads to memory leak, exactly our PROD met.
