Subject [jira] Commented: (HIVE-934) Rows loaded incorrect; should be suppressed.
Date Tue, 16 Mar 2010 01:24:30 GMT

    [ https://issues.apache.org/jira/browse/HIVE-934?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12845644#action_12845644

Thomas Lento commented on HIVE-934:

If it's hard to fix I'd vote for removing it or replacing "rows loaded" with "bytes loaded"
- I really don't care if the latter is wrong, and this way I still know that some data ended
up in the table.

Ideally, though, this number would be correct.

>                 Key: HIVE-934
>                 URL: https://issues.apache.org/jira/browse/HIVE-934
>             Project: Hadoop Hive
>          Issue Type: Bug
>            Reporter: Adam Kramer
>            Priority: Trivial
> 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. :)
