Subject Re: Hbase Row Key Scan
Date Tue, 24 Nov 2015 04:05:21 GMT
HI ,

You can use prefixfilter class while scan



byte[] prefix = Bytes.toBytes("key");		Scan scan = new Scan();		Filter
prefixFilter = new PrefixFilter(prefix);	
scan.setFilter(prefixFilter);	    ResultScanner resultScanner =
Main_Table.getScanner(scan);




Thanks

Beeshma
