Subject Re: Config Problems with HBase and Jetty
Date Wed, 20 Jan 2010 21:32:12 GMT
Yeah, we're just using the default so no zoo.cfg.  Permissions are fine as I
can ssh into any other hadoop box without password.  Although it looks like
permissions aren't set on the log directory.  I'm currently VPN'd, so maybe
its a networking issue??

Hbase shell is working:
hbase(main):009:0> scan 'Guts', {COLUMNS => ['user:theme'], LIMIT=>5}
ROW                          COLUMN+CELL

 -10095526042667             column=user:theme, timestamp=-10095526042667,
value=Frost
 -10095526042683             column=user:theme, timestamp=-10095526042683,
value=Frost
 -10095526042854             column=user:theme, timestamp=-10095526042854,
value=Frost
 -10095526042870             column=user:theme, timestamp=-10095526042870,
value=Frost
5 row(s) in 0.2570 seconds

Jetty is working:

// Substitute HBase config for test stringbuilder

StringBuilder builder = new StringBuilder();

        builder.append("Blah blah blah");

        response.getOutputStream().write(
                builder.toString().getBytes());

Outputs "Blah blah blah" to the screen.
