Subject Re: What do I loose if I run spark without using HDFS or Zookeeper?
Date Thu, 25 Aug 2016 16:18:03 GMT
You can use Spark on Oracle as a query tool.

It all depends on the mode of the operation.

If you running Spark with yarn-client/cluster then you will need yarn. It
comes as part of Hadoop core (HDFS, Map-reduce and Yarn).

I have not gone and installed Yarn without installing Hadoop.

What is the overriding reason to have the Spark on its own?

 You can use Spark in Local or Standalone mode if you do not want Hadoop
