> When creating a secondary index on a map type, for keys, the DESC TABLE output does not create correct DDL (it omits the keys part). So if someone uses describe to recreate a schema they could end up with a values index instead of a keys index.
> First, create a table and add an index:
> {noformat}
> CREATE TABLE test.foo (
>     id1 text,
>     id2 text,
>     categories map<text, text>,
>     PRIMARY KEY (id1, id2));
> create index on foo(keys(categories));|
> {noformat}
> Now DESC TABLE and you'll see the incomplete index DDL:
> {noformat}
> CREATE TABLE test.foo (
>     id1 text,
>     id2 text,
>     categories map<text, text>,
>     PRIMARY KEY (id1, id2)
> ) WITH CLUSTERING ORDER BY (id2 ASC)
> .......................snip..............................................
> CREATE INDEX foo_categories_idx ON test.foo (categories);
> {noformat}
