Hello: I'm working in a proyect, and i'm using hbase for storage the data, y have this method that work great but without the performance i'm looking for, so i want is to make the same but using mapreduce.
public ArrayList<MyObject> findZ(String z) throws IOException { ArrayList<MyObject> rows = new ArrayList<MyObject>(); Configuration conf = HBaseConfiguration.create(); HTable table = new HTable(conf, "test"); Scan s = new Scan(); s.addColumn(Bytes.toBytes("x"), Bytes.toBytes("y")); ResultScanner scanner = table.getScanner(s); try { for (Result rr : scanner) { if (Bytes.toString(rr.getValue(Bytes.toBytes("x"), Bytes.toBytes("y"))).equals(z)) { rows.add(getInformation(Bytes.toString(rr.getRow()))); } } } finally { scanner.close(); } return archivos; } the getInformation method take all the columns and convert the row in MyObject type. I just want a example or a link to a tutorial that make something like this, i want to get a result type as answer and not a number to count words, like many a found. My natural language is spanish, so sorry if something is not well writing. Thanths http://www.uci.cu
