[jira] [Commented] (ASTERIXDB-1601) CREATE TYPE failure as NPE (unsupported/untested feature?)

["Michael J. Carey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ASTERIXDB-1601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15429820#comment-15429820 ] 

Michael J. Carey commented on ASTERIXDB-1601:
---------------------------------------------

E.g., here's another document-allowed CREATE TYPE example that doesn't actually work (though no NPE :-)) if you try replacing the employment history for users with the renamed type:

CREATE TYPE EmploymentHistory AS [ EmploymentType ];

    CREATE TYPE GleambookUserType AS {
      id:         int,
      alias:      string,
      name:       string,
      userSince: datetime,
      friendIds: {{ int }},
      employment: [ EmploymentType ]
    };

If you change the above field to " .... employment: EmploymentHistory ... " you get:

org.apache.asterix.om.types.AOrderedListType cannot be cast to org.apache.asterix.om.types.ARecordType [ClassCastException]

My proposal would be to only allow CREATE TYPE to be used to create a new record type for now, which is all we ever use it for.  I can't even remember why all that other stuff was/is there - but - sure enough, it dates back to the reference manual for UC AsterixDB 2013... :-)

> I just tried something that I'd long forgotten about that's documented in the reference manual but basically never used - and it doesn't work.  I am thinking we should disable this (and other things like it), perhaps?  Here's what I did:
>     DROP DATAVERSE TinySocial2;
>     CREATE DATAVERSE TinySocial2;
>     USE TinySocial2;
>     CREATE TYPE MyUserTupleType AS CLOSED {
>       id: uuid, alias: string?, name: string
>     };
>    CREATE TYPE RenamedType AS MyUserTupleType;
> Here's what I got:
> Internal error. Please check instance logs for further details. [NullPointerException]
