Subject [jira] [Updated] (TAJO-503) HCatalogStore can't scan several hive databases.
Date Wed, 15 Jan 2014 07:11:20 GMT

     [ https://issues.apache.org/jira/browse/TAJO-503?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jaehwa Jung updated TAJO-503:
-----------------------------

    Attachment: TAJO-503.patch

I uploaded the patch, and I created a new RB https://reviews.apache.org/r/16901.

This bug was happened by HCatalogStore. Because when I made HCatalogStore, I didn't assign
db name to TableDesc. 

I already verified the patch on my local cluster.
After review it, I'll commit to tajo-cdh https://github.com/gruter/tajo-cdh.
