Targetting 4.1

Proposal

Take the existing:

hazelcast/hazelcast/src/main/java/com/hazelcast/map/impl/proxy/MapProxyImpl.java

Line 916 in 4fed159

 public <R> Iterator<R> iterator(int fetchSize, int partitionId, Projection<Map.Entry<K, V>, R> projection, 

And create a public API in IMap which differs from the above in that it:

1. does not require partitionId but work

String representations of dataset objects are used for previewing their contents from the terminal. When converting a Dataset object to a string, we build a table using ascii characters. The current table has fixed width columns that do not take full advantage of the terminal real estate if the dataset only contains a few columns.

echo $dataset;

The PR JuliaData/CategoricalArrays.jl#310 means that an array with elements of type Symbol can no longer be wrapped as a CategoricalArray.

This means all MLJ documentation and test code that uses symbols in categorical data must be refactored to use strings instead.

These repos, at least, need checking/refactoring, in order of priority:

• MLJ

• [ ]

Introduction
As a tester or developer, I want to have correct answer for Hepta FCPS sample so that I can use it in test scenarios to improve quality of the library.

Acceptance Criteria

• Introduce Hepta.answer that will contain cluster labels for points from Hepta.data.
• Add Hepta.answer to definitions.
