[jira] [Updated] (TAJO-475) Table partition catalog recap
[ https://issues.apache.org/jira/browse/TAJO-475?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Min Zhou updated TAJO-475:
--------------------------
Attachment: tajo-475.diff
This is a big patch, all test cases can go through. But that's a false image. see TAJO-505, this patch throws NPEs due to that bug, but tests can pass .. weird :)
Some of the changes don't directly related to this recap, but triggers some of the bug of tajo. If I didn't fix those bugs, this patch will fail in the test cases.
