CarbonSchemaReader don't support Array<string>
When we read schema from index file and the data include array<string> data type

run org.apache.carbondata.examples.sdk.CarbonReaderExample :
{code:java}
    Schema schema = CarbonSchemaReader
                .readSchemaInIndexFile(dataFiles[0].getAbsolutePath())
                .asOriginOrder();
            // Transform the schema
            String[] strings = new String[schema.getFields().length];
            for (int i = 0; i < schema.getFields().length; i++) {
                strings[i] = (schema.getFields())[i].getFieldName();
                System.out.println(strings[i] + "\t" + schema.getFields()[i].getSchemaOrdinal());
            }
{code}

and throw some exception:
