                 Key: DRILL-446
                 URL: https://issues.apache.org/jira/browse/DRILL-446

I am trying to load the data which is of the following format

{noformat}
{
    "test": "ABC",
    "test2": [1,2,3],
    "a": "drill"
}
{
    "test": "abc",
    "test2": [1,2,3,4],
    "a": "apache"
}
{noformat}

and executing *SELECT* query on the above data. While doing that I am getting 
the following exception

{noformat}
java.lang.ClassCastException: 
org.apache.drill.exec.vector.NullableVarCharVector cannot be cast to 
org.apache.drill.exec.vector.RepeatedVarCharVector
