Phabricator updated HIVE-2706:

Attachment: HIVE-2706.D1167.1.patch
kevinwilfong requested code review of "HIVE-2706 [jira] StackOverflowError when
using custom UDF after adding archive after adding jars".
Reviewers: JIRA
https://issues.apache.org/jira/browse/HIVE-2706
The issue was that the current thread's classloader and the classloader in
the conf differed due to the prehook updating only the current thread's
classloader with new jars. Now, it updates both classloaders, fixing the issue.
When a custom UDF is used in a query after add an archive, such as a zip
file, after adding jars, the XMLEncoder enters an infinite loop when
serializing the map reduce task, as part of sending it to be executed. This
results in a stack overflow error.
