I'm trying to use CQLSSTableWriter by following the simple example given in the Cassandra blog.
My project dependencies are:
compile 'org.codehaus.groovy:groovy-all:2.3.11'
compile 'com.datastax.cassandra:cassandra-driver-core:2.1.9'
compile 'org.apache.cassandra:cassandra-all:2.2.4'
testCompile group: 'junit', name: 'junit', version: '4.11'
Here is my code:
Application.groovy
package com.example
import org.apache.cassandra.io.sstable.CQLSSTableWriter
class Application {
public static void main(String[] args) {
def schema = """create table example.new_table (
name ascii,
value ascii
PRIMARY KEY (name));"""
def insert = """INSERT INTO example.new_table
(name, value)
VALUES ( ?, ? )"""
def outputDir = "/Users/me/datadump"
def writer = CQLSSTableWriter.builder()
.inDirectory(outputDir)
.forTable(schema)
.using(insert)
.build()
writer.close()
}
}
This code results in the following exception:

All the examples of using CQLSSTableWriter look pretty much exactly like my code. Do I have a version conflict with my dependencies? I'm thinking maybe because the exception is telling me that it can't even load the Tracing class.
