Help me

Sir,

  I follow the web link http://miguel.leugim.com.mx/index.php/tag/pharo/.
  I installed the Pharo smalltalk for Accessing Cassandra Database.


  PharoCore images and thrift0.4.0,cassandra0.6.6 are downloaded.
  And load the cassandra.st,thrift.st in the Pharo image cassandraclient.



  I added the following coding in the Pharo workspace to access Cassandra Database.

    "Insert 10000 values"
  [| cp result client |
  client := CassandraClient binaryOnHost: 'localhost' port: 9160.


  cp := ColumnPath new
  columnFamily: 'Standard1';
  column: 'col1'.
  1 to: 10000 do: [ :i |
  result := client insertKeyspace: 'Keyspace1'
  key: 'row', i asString

  columnPath: cp

  value: 'v', i asString
  timestamp: 1
  consistencyLevel: ((Cassandra enums at: 'ConsistencyLevel') at:
'QUORUM').]] timeToRun


    When executing this program it showing  "client := CassandraClient binaryOnHost: 'localhost' port: 9160." is undefined.

Did you file in the two files generated:

thrift/lib/st/thrift.st
gen-st/cassandra.st

This will create the CassandraClient class in your image. If they didn't
load, the class won't exist.

Also, make sure the Cassandra server is running in order to the client
to connect and write the data

Cheers
