      Description

      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:

      Exception
      Exception in thread "main" java.lang.ExceptionInInitializerError

      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:

      test.java
      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);
        }
      }
