Summary: Bulk data loading in Cassandra causing OOM
Key: CASSANDRA-7271
URL: https://issues.apache.org/jira/browse/CASSANDRA-7271
Project: Cassandra
Issue Type: Bug
Reporter: Prasanth Gullapalli
I am trying to load data from a csv file into Cassandra table using
SSTableSimpleUnsortedWriter. As the latest maven cassandra dependencies have
some issues with it, I have taken the _next_ beta (rc) version cut as suggested
in CASSANDRA-7218. But after taking it, I am facing issues with bulk data
loading
Here is the piece of code which loads data:
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();
}
}
On trying to run loadData, it is giving me the following exception:

Here are my GRADLE_OPTS: -Xms1024m -Xmx1024m -XX:MaxPermSize=256m -Xdebug
-Xrunjdwp:transport=dt_socket,address=9999,server=y,suspend=n
And my csv file hardly contains 2 lines of data. Not sure what is causing OOM
here? Is there some problem with the latest code I have taken or am I missing
something here?
