Subject [jira] [Commented] (HBASE-5564) Bulkload is discarding duplicate records
Date Tue, 13 Mar 2012 05:25:55 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13228221#comment-13228221

Lars Hofhansl commented on HBASE-5564:

@Laxman: so what you have in your CSV file is entries like:
rowA, colA, val1
rowA, colA, val2

And the expectation is that HBase should create two versions:
(rowA, colA, ts1) -> val1
(rowA, colA, ts2) -> val2

Seems like a pretty constructed case to me :)
How would know ahead of time how many versions you'd need to configure for your column family?
3 is the default, but what if you have 100 versions of the same row/col combo in your CSV

But anyway, having an option to specify a column for the TS is a good idea.
Do you want to take a stab at it Laxman?
