Zeppelin Notebooks and Solr

The concept of data science notebooks has been around for a while. Notebooks are web interfaces that allow creating and sharing live code, equations, visualizations and narrative text. They exist somewhere in data science workflows to serve data cleaning, transformation, numerical simulation, statistical modeling, data visualization and even machine learning. In a Python environment, Jupyter is prominent. In Java or Scala environment, Apache Zeppelin fits seamlessly. Though Jupyter can be used with a Java kernel and Zeppelin can be used with a Python interpreter, each one natively belongs to its own stack.

Realtime Log Analytics with Solr, Logstash, Banana and Beats

Logs are everywhere and usually generated in large sizes and high velocities. These logs can be used to obtain useful information and insights about the domain or the process related to these logs, such as platforms, transactions, system users, etc. In this post, a realtime web (Apache2) log analytics pipeline will be built using Apache Solr, Banana, Logstash and Beats containers.

However, in order to get the pipeline running, several integration aspects related to streaming data need to be addressed through settings and patches supplied through mounted volumes. The structure of these volumes can be as below:
