Subject Re: Config Problems with HBase and Jetty
Date Sat, 23 Jan 2010 18:25:04 GMT
Thanks for the tip.  I ended up doing an "ant clean" to delete all the build
directories because I started noticing things that were in there that
shouldn't have been.  I'm not sure why I didn't do that before.

Anyways, I ended up adding the hbase-site.xml and hbase-default.xml to my
conf directories (putting them in the lib with the binaries didn't work).  I
got the success message that I posted in a previous e-mail.

My scanner still wasn't working, so just to see if it was connecting to
HBase properly I did:

HBaseAdmin admin = new HBaseAdmin(config);
HTableDescriptor[] tables = admin.listTables();
response.getOutputStream().write(tables[0].getName());

And it worked! It properly passed the table name.  So now, its got to be my
scanner.  What I'd like to do is perform this hbase shell operation:

scan 'Guts', {COLUMNS=>['user:theme'], LIMIT=>10}

Here is my scanner code that apparently just hangs:
 Scan s = new Scan();
        s.addColumn(Bytes.toBytes("user"),Bytes.toBytes("theme"));
        ResultScanner scanner = table.getScanner(s);
        int count = 0;
        int limit = 10;
        Result res = null;


        try {
                for (Result rr = scanner.next(); rr != null; rr =
scanner.next()) {
                        if (count <= limit) {
                        response.getOutputStream().write( rr.getRow() );
                        count++;
                        }
                }
        } finally {
                scanner.close();
        }


any ideas??
