[jira] [Commented] (HIVE-18735) Create table like loses
transactional attribute
[ https://issues.apache.org/jira/browse/HIVE-18735?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16871185#comment-16871185 ]
Laszlo Pinter commented on HIVE-18735:
--------------------------------------
[~ekoifman] I provided a patch for this issue. I saw that, HIVE-18983 tried to address this problem as well, by copying all table properties. That patch is still in progress, and based on the review comments it is not likely will be merged in. I solved the current issue, by copying over just 3 properties (is_transactional, transactional_properties, bucketing_version), which were missing from the target table. I would appreciate, if you could review my patch. Thanks
