is it possible to store mongodb data on hdfs

Question

In my project, I'm challenging with data storage method. Firstly, in my project, there are streaming data in JSON format and most suitable db is MongoDB. I have to analyze data with Hadoop or Spark.

So, my conflict starts here: Can I store MongoDB collections in HDFS or must MongoDB and HDFS storage units be different? It is an important issue for my decision. Must I use Hadoop and MongoDB in same disk units or separate units?

Answer 1

由于存储方法，安全策略实现和存储机制本身不同，因此它们必须是不同的单元。
