if hbase has no secondary index, How hbase perform in column qualifier based scan like [scan 'tablename',{COLUMNS => ['column1']}]


I'm guessing you've already seen which basically is telling you that you'll need to have a second table whose rowkey is your "secondary index" and is only being used to find the rowkey needed for the actual table. The coprocessor strategy, as I understand it, is to just formalize & automate the "dual-write secondary index" strategy. Good luck and happy Hadooping!
