我正在尝试使用SSTableSimpleUnsortedWriter将数据从csv文件加载到Cassandra表中。以下是执行此操作的代码：
public void loadData(TableDefinition tableDefinition, InputStream csvInputStream){
createDataInDBFormat(tableDefinition, csvInputStream);
Path dbFilePath = Paths.get(TEMP_DIR, keyspace, tableDefinition.getName());
//BulkLoader.main(new String[]{"-d","localhost",dbFilePath.toUri().getPath()});
try {
JMXServiceURL jmxUrl = new JMXServiceURL(String.format(
"service:jmx:rmi:///jndi/rmi://%s:%d/jmxrmi", cassandraHost, cassandraJMXPort));
JMXConnector connector = JMXConnectorFactory.connect(jmxUrl, new HashMap<String, Object>());
MBeanServerConnection mbeanServerConn = connector.getMBeanServerConnection();
ObjectName name = new ObjectName("org.apache.cassandra.db:type=StorageService");
StorageServiceMBean storageBean = JMX.newMBeanProxy(mbeanServerConn, name, StorageServiceMBean.class);
storageBean.bulkLoad(dbFilePath.toUri().getPath());
connector.close();
} catch (IOException | MalformedObjectNameException e) {
e.printStacktrace()
}
FileUtils.deleteQuietly(dbFilePath.toFile());
}
private void createDataInDBFormat(TableDefinition tableDefinition, InputStream csvInputStream) {
try(Reader reader = new InputStreamReader(csvInputStream)){
String tableName = tableDefinition.getName();
File directory = Paths.get(TEMP_DIR, keyspace, tableName).toFile();
directory.mkdirs();
String yamlPath = "file:\\"+CASSANDRA_HOME+File.separator+"conf"+File.separator+"cassandra.yaml";
System.setProperty("cassandra.config", yamlPath);
SSTableSimpleUnsortedWriter writer = new SSTableSimpleUnsortedWriter(
directory, new Murmur3Partitioner(), keyspace,
tableName, AsciiType.instance, null, 10);
long timestamp = System.currentTimeMillis() * 1000;
CSVReader csvReader = new CSVReader(reader);
String[] colValues = null;
List<ColumnDefinition> columnDefinitions = tableDefinition.getColumnDefinitions();
while((colValues = csvReader.readNext()) != null){
if(colValues.length != 0){
writer.newRow(bytes(colValues[0]));
for(int index = 1; index< colValues.length; index++){
ColumnDefinition columnDefinition = columnDefinitions.get(index);
writer.addColumn(bytes(columnDefinition.getName()), bytes(colValues[index]), timestamp);
}
}
}
csvReader.close();
writer.close();
} catch (IOException e) {
e.printStacktrace();
}
}
在尝试运行loadData时，它会给出以下异常：

我正在使用gradle运行该程序。这是我的GRADLE_OPTS： -Xms1024m -Xmx1024m -XX：MaxPermSize = 256m -Xdebug -Xrunjdwp：transport = dt_socket，address = 9999，server = y，suspend = n
我的csv文件几乎不包含2行数据。不知道是什么原因造成了OOM。我在这里错过了一些配置吗？
