             Summary: Fix PageRank algorithm example
                 Key: FLINK-4593
                 URL: https://issues.apache.org/jira/browse/FLINK-4593
             Project: Flink
          Issue Type: Bug
          Components: Project Website
            Reporter: Alexander Pivovarov
            Priority: Minor


This page https://flink.apache.org/features.html shows the code which 
implements PageRank algorithm (Batch Processing Applications).

I noticed couple bugs in the code
Page class has pageId field
Adjacency has just id

but in the code I see
{code}pages.join(adjacency).where("pageId").equalTo("pageId"){code}

Also {code}Page(page.id, 0.15 / numPages){code}
