I seem to be having an issue when trying to connect to cassandra to php via
thrift and this is the issue when running this code:
?php
$GLOBALS['THRIFT_ROOT'] = '/usr/share/php/Thrift';
require_once $GLOBALS['THRIFT_ROOT'].'/packages/cassandra/Cassandra.php';
require_once $GLOBALS['THRIFT_ROOT'].'/packages/cassandra/cassandra_types.php';
require_once $GLOBALS['THRIFT_ROOT'].'/transport/TSocket.php';
require_once $GLOBALS['THRIFT_ROOT'].'/protocol/TBinaryProtocol.php';
require_once $GLOBALS['THRIFT_ROOT'].'/transport/TFramedTransport.php';
require_once $GLOBALS['THRIFT_ROOT'].'/transport/TBufferedTransport.php';
try {
// Make a connection to the Thrift interface to Cassandra
$socket = new TSocket('127.0.0.1', 9160);
$transport = new TBufferedTransport($socket, 1024, 1024);
$protocol = new TBinaryProtocolAccelerated($transport);
$client = new CassandraClient($protocol);
$transport->open();
/* Insert some data into the Standard1 column family from the default config */
// Keyspace specified in storage=conf.xml
$keyspace = 'Keyspace1';
// reference to specific User id
$keyUserId = "1";
// Constructing the column path that we are adding information into.
$columnPath = new cassandra_ColumnPath();
$columnPath->column_family = 'Standard1';
$columnPath->super_column = null;
$columnPath->column = 'email';
// Timestamp for update
$timestamp = time();
// We want the consistency level to be ZERO which means async operations on 1
node
$consistency_level = cassandra_ConsistencyLevel::ZERO;
// Add the value to be written to the table, User Key, and path.
$value = "foo...@example.com";
$client->insert($keyspace, $keyUserId, $columnPath, $value, $timestamp,
$consistency_level);
// Add a new column path to be altered.
$columnPath->column = 'age';
//Get a current timestamp
$timestamp = time();
// Update the value to be inserted for the updated column Path
$value = "24";
$client->insert($keyspace, $keyUserId, $columnPath, $value, $timestamp,
$consistency_level);
/*
use batch_insert to insert a supercolumn and its children using the standard
config
builds the structure *
Super1 : {
KeyName : {
SuperColumnName : {
foo : fooey value
bar : bar like thing
}
}
}
*/
// build columns to insert
$column1 = new cassandra_Column();
$column1->name = 'foo';
$column1->value = 'fooey value';
$column1->timestamp = time();
$column2 = new cassandra_Column();
$column2->name = 'bar';
$column2->value = 'bar like thing';
$column2->timestamp = time();
// build super column containing the columns
$super_column = new cassandra_SuperColumn();
$super_column->name = 'SuperColumnName';
$super_column->columns = array($column1, $column2);
// create columnorsupercolumn holder class that batch_insert uses
$c_or_sc = new cassandra_ColumnOrSuperColumn();
$c_or_sc->super_column = $super_column;
// create the mutation (a map of ColumnFamily names to lists
ColumnsOrSuperColumns objects
$mutation['Super1'] = array($c_or_sc);
$client->batch_insert($keyspace, 'KeyName', $mutation, $consistency_level);
/* Query for data */
// Specify what Column Family to query against.
$columnParent = new cassandra_ColumnParent();
$columnParent->column_family = "Standard1";
$columnParent->super_column = NULL;
$sliceRange = new cassandra_SliceRange();
$sliceRange->start = "";
$sliceRange->finish = "";
$predicate = new cassandra_SlicePredicate();
list() = $predicate->column_names;
$predicate->slice_range = $sliceRange;
// We want the consistency level to be ONE which means to only wait for 1 node
$consistency_level = cassandra_ConsistencyLevel::ONE;
// Issue the Query
$keyUserId = 1;
$result = $client->get_slice($keyspace, $keyUserId, $columnParent, $predicate,
$consistency_level);
print_r($result);
$transport->close();
} catch (TException $tx) {
print 'TException: '.$tx->why. ' Error: '.$tx->getMessage() . "\n";
}
?>
TTransport class was not loaded and not found in TSocket.php line 37.
Any ideas would be great?
Thanks
