Subject [jira] [Created] (CASSANDRA-9952) UDF with no parameters prevents cqlsh DESCRIBE from working
Date Sat, 01 Aug 2015 22:49:04 GMT
Jim Meyer created CASSANDRA-9952:
------------------------------------

             Summary: UDF with no parameters prevents cqlsh DESCRIBE from working
                 Key: CASSANDRA-9952
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9952
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
         Environment: ubuntu 64 bit, using ccm tool with a one node cluster, release 2.2.0
            Reporter: Jim Meyer
            Priority: Minor
             Fix For: 2.2.x


If I create a user defined function that takes no parameters like this:

cqlsh:test> CREATE FUNCTION no_parm() CALLED ON NULL INPUT RETURNS bigint LANGUAGE java
AS 'return System.currentTimeMillis() / 1000L;';

The function works fine in queries, but in cqlsh the describe command stops working:

    cqlsh:test> DESC KEYSPACE test;

    izip argument #1 must support iteration

If I drop the function, then describe starts working normally again.  It appears describe
assumes there is at least one argument for UDF's, but creating and using the functions does
not.
