question: public HBaseLogByRowkeyReader ( String table , String columnFamily , boolean includingAllQualifiers , List < String > qualifiers ) { this . table = table ; this . columnFamily = columnFamily ; if ( qualifiers != null ) { this . outputQualifiers = new byte [ qualifiers . size ( ) ] [ ] ; int i = 0 ; for ( String qualifier : qualifiers ) { this . outputQualifiers [ i ++ ] = qualifier . getBytes ( ) ; } } this . includingAllQualifiers = includingAllQualifiers ; }
target:  if includingAllQualifiers is true, then the fourth argument outputQualifiers is ignored if includingAllQualifiers is false, then need calculate based on the fourth argument outputQualifiers
