             Summary: CQLSSTableWriter close does not work - Regression bug: CASSANDRA-8281
                 Key: CASSANDRA-9052
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9052
             Project: Cassandra
          Issue Type: Bug
         Environment: cassandra-all:2.1.2
cassandra-all:2.1.3
            Reporter: Sebastian YEPES FERNANDEZ


Hello,

I have just noticed that the last C* version 2.1.3 reintroduced an old bug "CASSANDRA-8281".
When closing the CQLSSTableWriter after adding rows it generated the following Exception:

{code:title=Exception|borderStyle=solid}

Note that is this works correctly in 2.1.2 and not with 2.1.3, we can reproduce this issue 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);

  // These folders needs must exist: mkdir -p /tmp/kspc/t1
  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();

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