Subject [jira] [Commented] (HIVE-4014) Hive+RCFile is not doing column pruning and reading much more data than necessary
Date Fri, 01 Mar 2013 23:03:14 GMT

    [ 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?

> With even simple projection queries, I see that HDFS bytes read counter doesn't show
any reduction in the amount of data read.
