Subject [jira] Commented: (HADOOP-2508) [Hbase] TableOutputFormat could not assign a timestamp
Date Mon, 28 Jan 2008 21:39:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2508?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12563297#action_12563297

stack commented on HADOOP-2508:

Chatting, Jim had an idea where TableOutputFormat could take an HStoreKey with an empty column
field for its key instead of Text.  This would get a timestamp for a particular row into TableRecordWriter.write.

Also, if reducer wants to delete a cell, rather than add support for put/delete operations
-- iinstead just have the reducer output the special delete bytes cell value (See HLogEdit.deleteBytes).
