Subject [jira] [Commented] (HBASE-3967) Support deletes in HFileOutputFormat based bulk import mechanism
Date Wed, 15 Jun 2011 20:42:47 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13050014#comment-13050014
] 

Kannan Muthukkaruppan commented on HBASE-3967:
----------------------------------------------

Stack: <<If you removed the check for KV>> -- just making sure did you mean remove
the separate checks for Key class and Value class? It might still be a good idea to check
that it is at least a subclass of the expected class, no? Or does that check already happen
down the stream?

> During bulk imports, it'll be useful to be able to do delete mutations (either to delete
data that already exists in HBase or was inserted earlier during this run of the import).

> For example, we have a use case, where we are processing a log of data which may have
both inserts and deletes in the mix and we want to upload that into HBase using the bulk import
mechanism.
