I think there's a huge opportunity for whoever that can create Spark or Flink like framework that works in Node.js or at least has Node.js API.

It's a huge challenge to create a tool like that, but I believe there's an appetite for such tool. JS community is huge. JS is a flexible language that can conceptualize distributed computing well. JS community and developer ecosystem generally has superior emphasis on developer experience, outreach and education than the communities around existing tools.

Given how economically valuable companies that exist around big data distributed computing are, I think a company that can create an open source Node.js distributed computing tool will be like the next MongoDB, Elastic and Databricks.
