> Scenario : Need to read CSV, Write SSTable using CQLSSTableWriter and load it to the
keyspace. [Explained here|https://stackoverflow.com/questions/44713777/json-cassandra-field-value-parsing-using-antlr4]
. That was not working so tried a simple test case available here[https://github.com/apache/cassandra/blob/cassandra-3.11/test/unit/org/apache/cassandra/io/sstable/CQLSSTableWriterTest.java#L378]
> Which did not worked either. Following is what i tried.
> Created cql_keyspace3 with below table and types.
> {code:java}
> CREATE TYPE cql_keyspace3.tuple2 (a int, b int);
> CREATE TYPE cql_keyspace3.tuple3 (a int, b int, c int)
> CREATE TABLE cql_keyspace3.table3 ( k int, v1 list<frozen<tuple2>>, v2 frozen<tuple3>,
PRIMARY KEY (k));
> {code}
> ran code 
> {code:java}
>         final String KS = "cql_keyspace3";
>         final String TABLE = "table3";
>         final String schema = "CREATE TABLE " + KS + "." + TABLE + " (" + "  k int,"
+ "  v1 list<frozen<tuple2>>,"
>                 + "  v2 frozen<tuple3>," + "  PRIMARY KEY (k)" + ")";
>         File tempdir = Files.createTempDir();
>         File dataDir = new File(tempdir.getAbsolutePath() + File.separator + KS + File.separator
+ TABLE);
>         System.out.println(dataDir);
>         assert dataDir.mkdirs();
>         CQLSSTableWriter writer = CQLSSTableWriter.builder().inDirectory(dataDir)
>                 .withType("CREATE TYPE " + KS + ".tuple2 (a int, b int)")
>                 .withType("CREATE TYPE " + KS + ".tuple3 (a int, b int, c int)").forTable(schema)
>                 .using("INSERT INTO " + KS + "." + TABLE + " (k, v1, v2) " + "VALUES
(?, ?, ?)").build();
>         
>         
>         UserType tuple2Type = writer.getUDType("tuple2");
>         UserType tuple3Type = writer.getUDType("tuple3");
>         for (int i = 0; i < 100; i++) {
>             writer.addRow(i,
>                     ImmutableList.builder().add(tuple2Type.newValue().setInt("a", i *
10).setInt("b", i * 20))
>                     .add(tuple2Type.newValue().setInt("a", i * 30).setInt("b", i * 40)).build(),
>                     tuple3Type.newValue().setInt("a", i * 100).setInt("b", i * 200).setInt("c",
i * 300));
>         }
>         writer.close();
> {code}
