Hi there, I’m pretty new to Spark, and so far I’ve written my jobs the same way I wrote Scalding jobs - one-off, read data from HDFS, count words, write counts back to HDFS.
Now I want to display these counts in a dashboard. Since Spark allows to cache RDDs in-memory and you have to explicitly terminate your app (and there’s even a new JDBC server in 1.1), I’m assuming it’s possible to keep an app running indefinitely and query an in-memory RDD from the outside (via SparkSQL for example). Is this how others are using Spark? Or are you just dumping job results into message queues or databases?
