Thanks for this impressive PR. A minor comment: could you edit the title of
the PR to include more details than the issue ID (we can't do it because the
ASF is managing the github account). It's hard to track the PRs otherwise. I
would just go with the JIRA title: `[FLINK-1745] Add exact k-nearest-neighbours
algorithm to machine learning library`
