>  If you go through MetaStoreUtils.java you can see MAX_MS_TYPENAME_LENGTH is hard coded to 2000, but this can be set to higher value in mysql.Table create doesn't happen , for tables with higher type length. Different users can change this variable based on different use cases/metastore if this can be a config variable.
>   public static final int MAX_MS_TYPENAME_LENGTH = 2000;
>   public static final String TYPE_FROM_DESERIALIZER = "<derived from deserializer>";

>   static public String validateColumnType(String type) {
>     if (type.equals(TYPE_FROM_DESERIALIZER)) return null;
>     if (type.length() > MAX_MS_TYPENAME_LENGTH) {
>       return "type name is too long: " + type;
