Arpan Khandelwal created CASSANDRA-13633:
--------------------------------------------

             Summary: Data not loading to keyspace using sstable create via CQLSSTableWriter
                 Key: CASSANDRA-13633
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13633
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
         Environment: Linux
            Reporter: Arpan Khandelwal
             Fix For: 3.10
         Attachments: dataloading_result.png

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}

It generated sstable in "/tmp/1498224996687-0/cql_keyspace3" dir

Loaded data using following command 

{code:java}
/tmp/1498224996687-0/cql_keyspace3 $ sstableloader -d localhost table3-e6e0fa61581911e78be6a72ebce4c745/

||k||v1||v2||

find full result in attached snapshot.

Please let me know which version of cassandra I should which can allow me to load  reseverd
types, collections, UDT from sstable create using CQLSSTableWriter.
