Kannan Muthukkaruppan commented on HBASE-3967:
----------------------------------------------
Here are the relevant patches:
1) Original fix:
http://svn.apache.org/viewvc?view=revision&revision=1181568
2) Followup fix for tie-breaking when duplicate mutations with same
RowKey/ColKey/TS are put or deleted.. we want to make sure the "later" one
deterministically wins:
http://svn.apache.org/viewvc?view=revision&revision=1181589
Any volunteers to port this to trunk?

> 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.
