Subject php cql driver issues
Date Fri, 27 May 2011 00:17:12 GMT
Hi,

in an attempt to get my hands dirty with Cassandra I decide to participate
in driver development, but I have come across a number of
problems am unable to debug regardless of what I try.

The first issue is that the driver I developed is able to run cql commands
USE <keyspacename> CREATE KEYSPACE..., but the CREATE
COLUMNFAMILY... fails with no meaning full errors.

The same command works perfectly in Eric Evans
http://caqel.deadcafe.org/<http://www.google.com/url?sa=D&q=http://caqel.deadcafe.org/>but
in php no
success...

My Code
------------

phpCQLAutoloader::register();

$socketPool               = new TSocketPool();
$socketPool->addServer( "127.0.0.1", 9160 );
$socketPool->setDebug( true );

$framedTransport  = new TFramedTransport( $socketPool, true, true );
$bufferedProtocol =  new
TBinaryProtocolAccelerated( $framedTransport );
$cassandraClient  = new CassandraClient( $bufferedProtocol,
$bufferedProtocol );

try{

        echo "opening connection <br>";
        $framedTransport->open();

        try{

                        echo "Executing create column query <br/>";
                        //$query = "CREATE KEYSPACE southafrica WITH
strategy_options:replication_factor = 1 AND strategy_class =
'SimpleStrategy'";
                        $query  = "CREATE COLUMNFAMILY smoke (KEY text
PRIMARY KEY, monkey
text) WITH comparator = text AND default_validation = text";
                        $result = $cassandraClient->execute_cql_query(
$query ,
cassandra_Compression::NONE );

                        echo "|". print_r($result) . "|" . "<br>";

        }catch( cassandra_InvalidRequestException $exrs ){
                echo "COLUMNFAMILY error occuired -- <br> " . $exrs-
>getTraceAsString() . " <br>";

        }

                echo "closing connnection <br>";
        $framedTransport->close();

PHP Output
----------------

Cassandra log output
------------------------------

DEBUG 21:00:00,507 logged out: #<User allow_all groups=[]>
DEBUG 21:00:10,673 Disseminating load info ...
DEBUG 21:00:38,796 logged out: #<User allow_all groups=[]>
DEBUG 21:01:10,674 Disseminating load info ...
DEBUG 21:02:10,674 Disseminating load info ...
DEBUG 21:03:10,676 Disseminating load info ...
basically nothing happens in Cassandra in debug mode.

I'm totally lost...
