> Key: MRQL-81
> URL: https://issues.apache.org/jira/browse/MRQL-81
> Project: MRQL
> Issue Type: Bug
> Components: Run-Time/Flink, Run-Time/MapReduce, Run-Time/Spark
> Affects Versions: 0.9.6
> Reporter: Leonidas Fegaras
> Assignee: Leonidas Fegaras
> Priority: Critical
>
> Currently, query results that are persistent bags (such as Spark RDDs or
> Flink DataSets) are coerced to in-memory bags before they are printed. This
> needs to be done at any place in the query result. This came out when we used
> matrix factorization (query/factorization.mrql) because its output are the
> two matrix factors (datasets) in a tuple. It was reported by Ahmed Ulde. It
> will be fixed by adding a new case for tuple projection in the query
> evaluator that coerces persistent datasets to bags when they appear in the
> query output.
