----------------------------------
Summary: Concurrent queries in tez local mode fail
Key: HIVE-21682
URL: https://issues.apache.org/jira/browse/HIVE-21682
Project: Hive
Issue Type: Bug
Reporter: Todd Lipcon
Assignee: Todd Lipcon
As noted in TEZ-3420, Hive running with Tez local mode breaks if multiple
queries are submitted concurrently. As I noted
[there|https://issues.apache.org/jira/browse/TEZ-3420?focusedCommentId=16831937&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16831937]
it seems part of the problem is Hive's use of static global state for
IOContext in the case of Tez. Another issue is the use of a JVM-wide
ObjectRegistry
