------------------------------------
> Transformapply w/ column names fails with index-out-of-bounds
> -------------------------------------------------------------
>
> Key: SYSTEMML-1846
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1846
> Project: SystemML
> Issue Type: Bug
> Reporter: Matthias Boehm
> Assignee: Matthias Boehm
> Fix For: SystemML 1.0
>
>
> Given a simple transformapply scenario as shown in the following script
> {code}
> spec = "{ids: false, recode: [ zipcode, district, view ]}";
> [X, M] = transformencode(target=F, spec=spec);
> spec2 = "{ids: false, recode: [ zipcode ]}";
> X2 = transformapply(target=F[,1], spec=spec2, meta=M);
> {code}
> currently leads to index out-of-bounds exceptions because the column name
> zipcode is not found in the column names of the meta data frame. The root
> cause is a wrong assumption of sorted column names in the underlying
> implementation.
