[jira] [Commented] (TAJO-1201) Implement direct read of RCFile

    [ https://issues.apache.org/jira/browse/TAJO-1201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14958312#comment-14958312 ] 

Hyunsik Choi commented on TAJO-1201:
------------------------------------

We may not have any plan to improve RCFile because RCFile is deprecated in Hadoop ecosystem. So, I close this issue. We can reopen it when it is necessary later.
