[jira] [Comment Edited] (HIVE-11749) Deadlock of fetching
InputFormat table when multiple root stage
[ https://issues.apache.org/jira/browse/HIVE-11749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15139790#comment-15139790 ]

Hmm, I'm not very familiar with this code. This multi-root situation is MR-only, right? The patch makes sense (I wonder if all partition objects actually have different tabledesc objects - if not, reference equality would be enough and the problem would go away; otherwise, I wonder if comparing db + table names is enough). [~hagleitn] any input? git blame points at you ;) Otherwise +1
