[jira] Commented: (HBASE-581) Allow adding filters to TableInputFormat (At same time, ensure TIF and TOF are subclassable)

David Alves commented on HBASE-581:
-----------------------------------

Hi.
The main reason I couldn't subclass TIF is that HTable instance in TIF is package protected.
I then implemented an inner FilteredTableRecordReader that *can* receive a RowFilterInterface as argument, as this is not mandatory (the filter can be null) this could be a nice addition even to the HBase TIF, receiveing the filter class (and someway it's contructor arguments) by configuration. Even if this is not possible just allowing to set the record reader instance in TIF would make Overriding getRecordReader (and the TableSplit casts) unecessary.
