[jira] [Comment Edited] (TAJO-338) Improve StorageManager for column-partitioned table.

    [ https://issues.apache.org/jira/browse/TAJO-338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13834520#comment-13834520 ]

------------------------------------------------------------

When I adjust the patch about jira issue named [TAJO-284|https://issues.apache.org/jira/browse/TAJO-284], it made a error to scan hdfs blocks. So, I thought that Scanning just one file is sure the main cause of error. But I think now that I misunderstood about the cause. It needs to improve Planner compare than StorageManager and Scanner. So, I'm going to modify the issue title.
