             Summary: msgpack test case fails same as with json, problem with testing framework
                 Key: DRILL-6809
                 URL: https://issues.apache.org/jira/browse/DRILL-6809
             Project: Apache Drill
          Issue Type: Bug
            Reporter: jean-claude


I'm trying to write a test case for a repeated map scenario. However testing framework is unable to infer the schema of the resultset? I'm using the API correctly?
 
Thanks

// create a test file
    try (OutputStreamWriter w = new OutputStreamWriter(new FileOutputStream(new File(testDir, "test.json")))) {
      w.write("\{\"arrayOfMap\":[{\"type\": 3, \"data\": 44}]}\n");
    }
 
// read the test file
    String sql = "select * from `dfs.data`.`test.json`";
    RowSet actual = client.queryBuilder().sql(sql).rowSet();
 
// error outputted
java.lang.NullPointerException: null
