I'm installing hdp and Ambari ask me to choose the services which I want to install. I see, that Spark 2.0 is still marked as Technical Preview. Is this correct?
I want to use it for my study, so sould I install Spark, Spark 2.0, or Spark+Spark2.0? I prefer Spark 2.0, but I'm not sure if it is stable enough and if not, can I install both at the same time without any problem?
