["Alexander Pivovarov (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-4593?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexander Pivovarov updated FLINK-4593:
---------------------------------------
    Description: 
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}

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

Also, the code in not formatted (missing spaces)
{code}Page(n, 0.85*page.rank/adj.neighbors.length){code}
