Let’s create your first Grafana dashboard

In my previous blog, we discussed the setup of Grafana-Graphite for JMX monitoring.  Now we will create a first Grafana dashboard where we will create Grafana queries to visualize JMX metrics stored in Graphite. As we know, Grafana UI runs on http://localhost:3000/ by default so let’s open the URL in the browser with the default username and password which is admin: admin After login either Continue Reading

Scrum vs Extreme Programming! Let’s see the difference!

So in this blog we will discuss all 3 Continue Reading

Apache Spark : Spark Union adds up the partition of input RDDs

Some days back when I was doing union of 2 pair rdds, I found the strange behavior for the number of partitions. The output RDD got different number of partition than input Rdd. For ex: suppose rdd1 and rdd2, each have 2 no of partitions and after union of these rdds I was expecting same no of partitions for output RDD, but the output RDD got the Continue Reading
