Subject [jira] Commented: (HIVE-934) Rows loaded incorrect; should be suppressed.
Date Tue, 14 Dec 2010 22:20:03 GMT

    [ https://issues.apache.org/jira/browse/HIVE-934?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12971438#action_12971438

Adam Kramer commented on HIVE-934:
----------------------------------

Another option, provided by Greg, would be to actually disclose where this number comes from.
If it's an estimate based on something, have the message read "estimated X lines based on
Y."

> Rows loaded incorrect; should be suppressed.

> For several queries, Hive reports "rows loaded" at the bottom, e.g.,
> 928955 Rows loaded to akramer_mem_updates2
> ...however, this number is not always correct. "Rows loaded" should be the same as the
number of rows in the table after the table is created. In the above case, select count(1)
from akramer_mem_updates2 returns 2649223; this is incorrect.
> This has been noted for a long time; the basic response to reports of this problem is
"Yeah, rows loaded is wrong, you should ignore it." If this is so, it should stop being reported
by Hive entirely (or it should only be reported in cases where it is correct).
> Or, it could be fixed. :)
