> 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.
