----------------------------------------
Summary: 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
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.
