             Summary: CQLSSTableWriter: close does not work + more than one table throws ex
                 Key: CASSANDRA-8808
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8808
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Sebastian YEPES FERNANDEZ
             Fix For: 2.1.4, 2.1.0


I have encountered the following two issues:
 - When closing the CQLSSTableWriter it just hangs the process and does nothing. (https://issues.apache.org/jira/browse/CASSANDRA-8281)
 - When writing more than one table throws ex. (https://issues.apache.org/jira/browse/CASSANDRA-8251)

These issue can be reproduced with the following code:
{code:title=test.java|borderStyle=solid}
import org.apache.cassandra.config.Config;
import org.apache.cassandra.io.sstable.CQLSSTableWriter;

public static void main(String[] args) {
  Config.setClientMode(true);

  CQLSSTableWriter w1 = CQLSSTableWriter.builder()
    .inDirectory("/tmp/kspc/t1")
    .forTable("CREATE TABLE kspc.t1 ( id  int, PRIMARY KEY (id));")
    .using("INSERT INTO kspc.t1 (id) VALUES ( ? );")
    .build();

  CQLSSTableWriter w2 = CQLSSTableWriter.builder()
    .inDirectory("/tmp/kspc/t2")
    .forTable("CREATE TABLE kspc.t2 ( id  int, PRIMARY KEY (id));")
    .using("INSERT INTO kspc.t2 (id) VALUES ( ? );")
    .build();

  try {
    w1.addRow(1);
    w2.addRow(1);
    w1.close();
    w2.close();
  } catch (Exception e) {
    System.out.println(e);
  }
}
{code}

I have just tested the in the cassandra-2.1 branch and the issue still persists.
I have also tried this with this patch: https://issues.apache.org/jira/browse/CASSANDRA-8251
