[jira] [Commented] (HIVE-4014) Hive+RCFile is not doing column
pruning and reading much more data than necessary
[ https://issues.apache.org/jira/browse/HIVE-4014?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13591058#comment-13591058 ]
Vinod Kumar Vavilapalli commented on HIVE-4014:
-----------------------------------------------
Okay, I cannot reproduce this on trunk, though I was consistently hitting this on hive-0.10. I'll try hive-0.10 again to be sure some other patch fixed this.
[~tamastarjanyi], what version are you using?
