Hadoop does not use the default java serialization framework for performance reasons. It has it’s own serialization format writables , which is fast and compact but not interoperable. For that hadoop

Any java program can read files from HDFS, given the dependencies. In this blog we will read a file from HDFS and print it’s contents on console. The

Hadoop Supports many input/output file formats. In this blog we will see how to read a text file and we will save the results in Sequence file format.

NodeMCU has on analog channel which is configured to read the System voltage, we can configure it to sample the external pin. The ADC seems a bit jumping

ESP8266-01 version comes with a AT based firmware, you need a application processor/controller to solve a problem. if your use case doesn’t require lot of GPIO (ESP has

We have seen how to send the arduino serial content as email here, in this blog we will see how to send an email to arduino.Instead of simply

In this blog we will build Intruder detector using NodeMCU/ESP8266, more of like a burglar alarm. We will be using a IR reflection based sensor. The sensor working

In this blog we will see how to change PWM duty cycle of NodeMCU (PWM control) from a remote client. Our hard ware will be nodeMCU and on

In this blog we will see how to setup unit testing for a java project. Fist create a java project and a simple class. I created a simple
