> Considering to batch delete data in table which we load from external
> files,this feature add a switch key to enable batch delete.
> First,using the file we load to table and the bulkoutput function of
> ImportTsv to generate hfiles in hdfs which contain the keyvalue of
> 'DeleteFamily' marker .Then the tool of
> org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles is used to load
> hfiles into table intending to cover the data of whole family we need to
> delete.
