[jira] [Commented] (TAJO-338) Add Query Optimization Part for
Column-Partitioned Tables
[ https://issues.apache.org/jira/browse/TAJO-338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13852458#comment-13852458 ]
JaeHwa Jung commented on TAJO-338:
----------------------------------
Awesome!
It looks great. :)
But you have to update HCatalogStore because It converted Partitions to PartitionDesc.
You can find build failure using HCatalogStore as follows:
{code:xml}
*mvn clean install -Phcatalog-0.12.0*
